(1) Dibromotriphenylantimony(V), [SbBr2(C6H5)3], M(r) = 513.0, orthorhombic, Fdd2, a = 24.179 (8), b = 10.282 (3), c = 14.234 (5) angstrom, V = 3538.7 angstrom3, Z = 8, D(x) = 1.93 g cm-3, Mo Kalpha radiation (graphite monochromator), lambda = 0.7107 angstrom, mu = 63.6 cm-1, F(000) = 1952, T = 294 K, R = 0.0428, wR = 0.0451, for 96 least-squares parameters and 739 unique observed reflections with I > 3sigma(I). The Sb atom and one of the phenyl groups lie on a twofold axis. (2) Dichlorotriphenylantimony(V), [SbCl2(C6H5)3], M(r) = 423.9, orthorhombic, P2(1)2(1)2(1), a = 10.882 (4), b = 12.127 (4), c = 12.986 (4) angstrom, V = 1713.7 angstrom3 Z = 4, D(x) = 1.64 g cm-3, Mo Kalpha radiation (graphite monochromator), lambda = 0.7107 angstrom, mu = 19.3 cm-1, F(000) = 832, T = 294 K, R = 0.0272, wR = 0.0274, for 190 least-squares parameters and 1555 unique observed reflections with I > 3sigma(I). In both compounds, the Sb atom is in trigonal bipyramidal coordination with two axial halogen atoms [Sb-Br 2.632 (1); Sb-Cl 2.468 (2), 2.458 (2) angstrom] and three equatorial phenyl groups [Sb-Cl 2.11 (1) and 2.12 (1) angstrom for the bromide and 2.084 (2), 2.100 (2) and 2.106 (2) angstrom for the chloride].
