μ₂-Oxalato-bis­[triphen­yl(thio­urea-κS)tin(IV)]

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 Sn^IV 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.
