✦ Synopsis

The crystal structure of dichlorobis(ethyl3oxobutanoato)tin,'IV), ClzSn(CeH~03)2, has been determined from three-dimensional

X-ray diffraction data. Unit-cell dimensions are a = 11.818(5), b = 10.408-(4), c = 14.155(6) A, space group Pbcn, 2 = 4, D, = 1.71 g cm-' and D, = 1.74 g cm-'. The structure was solved by the heavy-atom method from intensity data collected by diffractometric methods and refined by fill-matrix least-squares methods to R = 0068 for 1299 observed reflections. The coordination about the Sn atom is a slightly distorted octahedron. The ethyl 3oxobutanoate acts as a bidentate ligand bonding to the tin atom through the oxygen atoms. The chloro groups are in cis positions and the molecular symmetry is C,. Sn-O(eq) bond length is 2.101(15) A The Sn-O(ax) and Sri-Cl distances are 2.066(15) and 2.347( 7) A respectively. The Cl-Sri-Cl angle is 98.1(l)'.
