Abstract

In the title compound, [Sn4(CH3)8(C8H9O2)2Cl2O2], the tetranuclear complex molecule has crystallographically imposed inversion symmetry. The coordination polyhedron about the two central Sn atoms is distorted trigonal–bipyramidal, whilst the two peripheral metal atoms bonded to the carboxylate groups have a distorted octahedral coordination geometry. In the crystal, molecules are connected by long Sn⋯O contacts [3.139 (11) Å], forming chains along [011].
