ABSTRACT
The asymmetric unit of the binuclear title compound, [Sn(2)(C(2)O(4))(C(6)H(5))(6)(CH(4)N(2)S)(2)], consists of one half of the organotin(IV) mol-ecule. The remainder is generated by a twofold rotation axis passing through the mid-point of the oxalate C-C bond. The Sn(IV) atom exhibits a distorted trigonal-bipyramidal coordination environment with the phenyl groups in equatorial positions and the thio-urea and the monodentately bridging oxalate anion in axial positions. The mol-ecules are linked through N-Hâ¯O hydrogen bonds involving the amino group of the thio-urea ligand and the uncoordinating oxalate O atoms, forming layers parallel to (001). Weak C-Hâ¯O inter-actions are also present.
