Instead of a slightly distorted (cubic) diamondlike structure (zinc-blende, sphalerite) of 1 a slightly distorted hexagonal diamondlike structure (wurtzite) would be a reasonable alternative. However, according to model building the interpenetration possibilities of several wurtzite-type lattices appear more restricted than of diamond-type lattices. A very readable monograph on diamond has recently appeared Adam Hilger: Bristol, U.K. For hexagonal diamond (lonsdaleite), see: (a) Frondel, C.; Marvin, U. B. Nature (London) 1967, 214, 587. Hanneman, R. E.; Strong, H. M.; Bundy, F. P. Science (Washington, D.C.) 1967, 155, 995.

Thomas, E. L.; Alward, D. B.; Kinning, D. J.; Martin, D. C.; Handlin, D. L.; Fetters, L. J. Macromolecules 1986, 19, 2197. Note the interesting relationships with mathematical minimal surfaces discussed in these papers. It is noted further that the lattice type of the intermetallic Zintl phase NaTl corresponds to a mixed double-diamond structure with a diamond lattice formed by the thallium atoms and another symmetrically interpenetrating one (cf., Figure 3) of the same size made up of the sodium atoms. See: Lan-dolt-Börnstein Zahlenwerte und Funktionen aus Physik, Chemie, Astronomie, Geophysik und Technik; Springer: Berlin, West Germany, 1955; Vol. 1, Part 4, p 30. Other inorganic examples of double-diamondlike structures are provided by the silicate mineral neptunite, by Cu2O (cuprite), Zn(CN)2 and Cd(CN)2, and by three high-pressure modifications of ice: Cannillo, E.; Mazzi, F.; Rossi, G.

The tetragonal crystals of 1 are optically uniaxial positive: ncD(||c) = 1.6512 (5), n0D(⊥c) = 1.5909 (5); n̅D = (1.6512 + 1.5909 + 1.5909)/3 = 1.6110. These refractive indices were measured by O, Mcdenbach. Bochum, to whom we extend our appreciation, on a microrefractometer recently designed by himself

For comparison with 5, the crystal structure of pentaerythritol, C-(CH2OH)4, appears to be of interest. This tetraalcohol also crystallizes tetragonally yet does not form diamondoid lattices. Presumably, this is at least partly due to the less suitable directionality of the hydrogen bonds of pentaerythritol as suggested by model considerations. Numerous crystallographic studies on pentaerythritol have been reported; see, e.g.: Llewellyn, F. J.; Cox, E. G.; Goodwin, T. H. J. Chem. Soc. 1937, 883.
