tetrachloroal~minate. The crystals are orthorhombic a = ii.i16(2), b = 16.923(3), c = 21.848(4)A, z = 8, space group Pbca, R = 0.088 for 2254 reflections. The AICI~ anion has an almos t ideal tetrahedral configuration, and the average distance is AI--AI 2.134(3) A. The cation has idealized C s symmetry, while the bond lengths in it are close to those inohexamethylbenzolonium tetrachloroaluminate. The C(1) atom
