[mu]2-Oxalato-bis[triphenyl(thiourea-[kappa]S)tin(IV)]

Abstract: The asymmetric unit of the binuclear title compound, [Sn2(C2O4)(C6H5)6(CH4N2S)2], consists of one half of the organotin(IV) molecule. The remainder is generated by a twofold rotation axis passing through the mid-point of the oxalate C-C bond. The SnIV atom exhibits a distorted trigonal-bipyramidal coordination environment with the phenyl groups in equatorial positions and the thiourea and the monodentately bridging oxalate anion in axial positions. The molecules are linked through N-H...O hydrogen bonds involving the amino group of the thiourea ligand and the uncoordinating oxalate O atoms, forming layers parallel to (001). Weak C-H...O interactions are also present.
