STRUCTURE OF (RF)2(CL)SNIV(MU-2-O)SNIV(CL)(RF)2 - RF = 2,4,6-TRIS(TRIFLUOROMETHYL)PHENYL

Mu-Oxo-bis{chlorobis[2,4,6-tris(trifluoromethyl)phenyl]tin}, C36H8Cl2F36OSn2, M(r) = 1448.7, monoclinic, P2(1)/n, a = 15.100 (1), b = 14.830 (1), c = 20.169 (2) angstrom, beta = 95.18 (1)-degrees, V = 4498.1 (6) angstrom 3, Z = 4, D(x) = 2.14 g cm-3, lambda(Mo K-alpha) = 0.71069 angstrom, mu = 14.1 cm-1, F(000) = 2760, T = 153 K, R = 0.039 for 6140 observed reflections. This dimeric compound is an oxidation product of Sn(II)(R(f))2. The two Sn(IV)(Cl)-(R(f))2 groups are bridged by a mu-2-oxo moiety [Sn(1)-O(1)-Sn(2) = 144.8 (2)-degrees]. The geometry at the Sn atoms is distorted tetrahedral. Average bond lengths to the Sn atoms are as follows: Sn-O 1.937 (3), Sn-Cl 2.315 (1) and Sn-C 2.194 (5) angstrom.
