Abstract
Abstract Dichlorobis(2,4-pentanedionato)tin(IV), SnCl 2 (C 5 H 7 O 2 ) 2 , crystallizes in the monoclinic space group C2/c with a = 13.937(4), b = 7.864(2), c = 13.746(4) A , β = 107. 75((1),°, Z = 4, D c = 1. 796(1) g/cc, and D m = 1.78 g/cc. The crystal structure was solved by conventional Patterson and Fourier methods using 2053 independent reflection intensities measured by the θ–2θ scan method with a scintillation counter. Refinement by the full-matrix least squares method gave a final agreement factor R(F) of O.036. The structure consists of discrete molecules with the tin atom in a distorted octahedral configuration. The chloro ligands are in cis position and are related by a crystallographic two-fold axis. The important average bond distances are SnCl (2.345(1) A ), SnO (2.058(7) A ), CO (1.282(8) A , CC (conjugated) (1.386(12) A ), and CC(sp 3 ) (1.488(5) A ). The ClSnCl angle is 96.86(5)°.
