(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.
