Bis(triphenylstannyl) thiophene-2,5-dicarboxylate

Abstract

Molecules of the title compound, [Sn2(C6H5)6(C6H2O4S)], lie on inversion centres with the central thiophene ring disordered equally over two orientations. The carboxylate groups are approximately coplanar with the thiophene ring [dihedral angle = 4.0 (1)°] and the Sn—O bond distance of 2.058 (4) Å is comparable to that in related organotin carboxylates.
