  Dr. P.H. Emmett

  Mellon Institute of Industrial Research

  Pittsburgh 13, Pa.

  Dear Paul:

  I am very glad to have your letter of July 25, and to know that the samples of silica gel that you studied have the same surface areas and pore distributions.

  I shall ask Dr. Dickey to write to you separately. I believe that he can send you samples of the dyes in order that you can verify that the gels that you used have specificity. I do not know whether the decay of specific properties goes on so rapidly that they would already have lost this specificity, but he can give you some information on that point.

  I was sorry to miss you in Pittsburgh. Ava Helen was not with me - she and Crellin went directly through to Boston, where I visited young Linus and his family later. He and Anita have a fine boy, a little over a month old now.

  Sincerely yours,

  Linus Pauling:W

  Dr. R. C. Menzies

  Department of Chemistry

  Mid-Essex Technical College

  Chelmsford, England

  Dear Dr. Menzies:

  I have been interested to read your article with Dr. Lile in the last issue of the Journal about complex formation by the trimethyl platinic group.

  In the article you refer to the structure investigation of trimethyl platinum chloride by J. H. Sturdivant and R. E. Rundle, referred to in my book. The investigation of this substance and of platinum tetramethyl was completed a number of years ago by Dr. Rundle and Professor Sturdivant, and a detailed account of the results was published in the Journal of the American Chemical Society, 69, 1561 (1947).

  Sincerely yours,

  Linus Pauling:W

  Some predicted structures, including AB₁₂ and AB₆

  I think that it should be possible to show the existence of compounds AB₁₂ and AB₆, and perhaps of certain other compounds, corresponding to superstructures on cubic closest packing, some of the other structures being superstructures on hexagonal closest packing.

  Let us first take the case in which atom A is surrounded by 12 atoms of B, the group AB₁₂ being equivalent to one another, and with all 13 atoms occupying points of either the cubic or hexagonal closest packed arrangement, or some similar arrangement. Let us find a structure in which the group AB₁₂ are crystallographically equivalent and all of the points of the closest packed arrangement are occupied.

  We have 13 atoms. The number 13 can be represented as 1²+3x2², and hence a close packed layer can be divided into units containing 13 atoms. It is seen on examining these units that they correspond to an atom A with 6 atoms B arranged around it at each lattice point, and 2 triangular groups of 3 atoms B in addition. The orientations of the triangles are such as to cause the layers above and below to be arranged in the way corresponding to hexagonal closest packed. Accordingly the unit of structure is rhombohedral, containing 1 AB₁₂. The length of the corresponding C axis is the same as the body diagonal of cubic closest packing, and the length of the A axis is √13 x the interatomic distance.

  I think that it should be possible to show the existence of this rhombohedral structure, in well-annealed solid solutions of atoms A in a metal B which crystallizes in cubic closest packing. It is very interesting to note that many metals that crystallize in cubic closest packing dissolve other metals with the same atomic radius just to the extent corresponding to the formula AB₁₂.

  Sometimes the solubility is somewhat less than this, indicating that the activities of the metals in the melt are not such as to permit the ordered arrangement to be achieved, there being instead some extra atoms B occupying interstitial points between the groups AB₁₂.

  I propose that you suggest to one of the new graduate students who come to see you at the beginning of the new term (I shall be away on Monday, September 26, but I shall want to see the new students during the next day or so) that he take this as his problem. This would involve the preparation of a number of alloys of composition AB₁₂, perhaps including CdAu₁₂, NaPb₁₂, SiCu₁₂, SnCu₁₂, ZnCu₁₂, MgCu₁₂, HgCu₁₂, SnPt₁₂, MnCu₁₂, SnNi₁₂, HgPb₁₂, HgTl₁₂ (kept above the β-α transition of thallium), etc. It might well be necessary to anneal the alloys in a number of different ways, and to test for superstructures in each case. Perhaps the most effective way would be to reduce the temperature of a furnace very slowly from a high enough temperature to room temperature, to permit superstructure to be formed no matter what the temperature is at which the procedure would occur.

  In case that an alloy of the proper composition does not form a super-structure AB₁₂, or in case it is not possible to dissolve this much A in the phase, it might be worth while to carry on experiments to show the complexes AB₁₂ in the alloy. This might be done with, say, Cu₁₂Hg; a radial distribution might prove that mercury atoms are not present adjacent to one another, nor even with ligands shared. However, this would be a more difficult problem, applicable only in a few cases, and I think that it should be possible to demonstrate the existence of a superstructure.

  In the case of metals with hexagonal close packing, I believe that there is no way to achieve the formula AB₁₂ with independent AB₁₂ groups. However, if there are extra atoms B I think that an arrangement based on hexagonal close packing can be constructed - I have not attempted to do so. Probably a compound AB₁₃ based on hexagonal closest packing could exist with AB₁₂ groups equivalent to one another, and an additional interstitial B atom. It might be worth while to examine the lithium-magnesium system, to see if the compound LiMg₁₃ exists.

  The next case of interest is that in which atom A is surrounded by 12 atoms B, each of which is shared with one other AB₁₂ group. The composition of such a phase would be AB₆. Since the number 7 can be represented as 2² + 3 x 1², and since the atoms A with a hexagon of 6 atoms B around the corresponding unit in the hexagonal plane are so related to one another as to permit their corners to be connected by 3 triangles, a structure satisfying our requirements that the complexes AB₁₂ be equivalent can be formulated. It is based on a rhombohedral lattice, the corresponding hexagonal unit having its c axis equal to the body diagonal of the close packed cube and the a axis being equal to √7 x the interatomic distance.

  I suggest that reported compounds with formula AB₆ be prepared and investigated to see if they correspond to this interesting rhombohedral structure. Reported compounds include WNi₆, NaHg₆, LiHg₆ (?), CeCu₆, CsHg₆, and a few others. I do not think that CeCu₆ is interesting in this respect, because the atoms involved do not have the same atomic radii, but most of the others are worth preparing and investigating (anyway I think that Knop and the people in Norway have already studied CeCu₆). In addition, the student working on this problem might well prepare a number of solid solutions of A in B, with B having the cubic close packed arrangement, and then anneal them and look for superstructure lines. The composition should correspond to the formula AB₆. Among the compounds that might be sought for in this way are MhCu₆, HgPb₆ (superstructure lines perhaps wouldn't show up) FeZr₆, HgTl₆, LiMg₆. I think that the last three at room temperature are based on hexagonal C.P.

  And so it might be better to investigate the compositions AB₇.

  Intermetallic compounds to be investigated

  In a paper by E. Zintl and O. Treusch, Z. phys. Chem., B34., 225 (1936) abstracted in Strukturbericht, 4, p. 237, there is a discussion of a compound with composition very close to CuGa₂. φ phase ,the unit of structure is tetragonal and the three atoms in the unit are put in the position 000, 1/2 1/2 x, and 1/2 l/2 y, x = 0.70, y = 0.27. The authors say that the intensities show that y is not equal to 1 - x. They contend that the copper atom is at 1/2 1/2 y.

  I think the structure is probably right, except that the copper atom should be at 000, and x should be equal to 1 - y, these two positions being crystallographically equivalent, and occupied by gallium atoms. With such a structure each gallium atom would have coordination number 5, somewhat similar to its environment in the element itself. Copper has coordination number 8 (or 12, if a rather long distance between neighboring copper atoms is considered to be significant).

  The crystals are apparently easily prepared - they show basal cleavage, and single crystal diagrams were taken by the investigators.

  Because of the interesting characteristics of this structure, I suggest that you have somebody make crystals and reinvestigate the structure, in order to check on the position of the gallium atoms. I suggest also that an effort be made to obtain crystals of other compounds with the same structure, such as AgGa₂.
