Thesis (Ph.D.)--Boston University / The crystal structure of an aluminum boride with a high boron content, "AlphaA1B12", has been investigated. X-ray diffraction photographs of levels zero to seven were obtained using Weissenberg equi-inclination techniques on a crystal rotating about the b-axis. The tetragonal unit cell axes are a = b = 10.17 A. and c = 14.28 A. The space group is P 4 12 12 or its enantiomorph P 4 32 12. The number of formula units per unit cell, calculated using the experimental density of 2.55 g./cc., is 14.4.[TRUNCATED]
