Abstract:
In the title compound, [Sn(C6H5)3(C5H8NS2)], the Sn(IV) atom adopts a distorted SnC3S tetra-hedral coordination geometry [spread of bond angles = 94.43 (7)-120.74 (7)°]. A short intra-molecular Sn⋯S contact [3.0270 (9) Å] occurs and two intra-molecular C-H⋯S inter-actions help to establish the conformation. Three of the methyl-ene groups of the pyrrolidine-1-carbodi-thio-ate ligand are disordered over two sets of sites of equal occupancy. In the crystal, very weak C-H⋯S inter-actions link the mol-ecules into a three-dimensional network, with both S atoms acting as acceptors.
