Di-chlorido-dimethyl-bis-(thio-urea-κS)tin(IV)

Abstract

The title compound, [Sn(CH3)2Cl2(CH4N2S)2], crystallizes with two half-mol-ecules in the asymmetric unit. Both mol-ecules are completed by inversion symmetry with the two Sn(IV) atoms located on inversion centers. The metal atoms have distorted octa-hedral coordination environments defined by two Cl atoms, two C atoms of methyl groups and two thio-urea S atoms. In the crystal, mol-ecules are linked via N-H⋯Cl and N-H⋯S hydrogen bonds, forming a three-dimensional structure.

A view of the structures of the two independent molecules of the title compound, with atom labelling. Displacement ellipsoids are drawn at the 50% probability level. Both atoms Sn1 and Sn2 occupy inversion centers. Non-labelled atoms are generated by symmetry codes -x + 1, -y + 1, -z + 1 (Sn1) and -x, -y, -z (Sn2).
