Popis:	(1) Dibromotriphenylantimony(V), [SbBr 2 -(C 6 H 5 ) 3 ], M r =513.0, orthorhombic, Fdd2, a=24.179 (8), b=10.282 (3), c=14.234 (5) A, V=3538.7 A 3 , Z=8, D x =1.93 g cm -3 , Mo Kα radiation (graphite monochromator), A=0.7107 A, μ=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>3σ(I). The Sb atom and one of the phenyl groups lie on a twofold axis. (2) Dichlorotriphenylantimony(V), [SbCl 2 (C 6 H 5 ) 3 ], M r = 423.9, orthorhombic, P2 1 2 1 2 1 , a=10.882(4), b=12.127(4),c=12.986(4) A, V=1713.7 A 3 , Z=4, D x =1.64 g cm -3 , Mo Kα radiation (graphite monochromator), λ=0.7107 A, μ=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>3σ(I).
