Dichlorobis(2,4-pentanedionato)tin(IV), SnCl2(C5H7O2)2, crystallizes in the monoclinic space group C2/c with a = 13.937(4), b = 7.864(2), c = 13.746(4) Å, β = 107. 75((1),°, Z = 4, Dc = 1. 796(1) g/cc, and Dm = 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 SnCl (2.345(1)Å), SnO (2.058(7)Å), CO (1.282(8)Å, CC (conjugated) (1.386(12)Å), and CC(sp3) (1.488(5)Å). The ClSnCl angle is 96.86(5)°.
