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 SnO contacts [3.139 (11) Å], forming chains along [011].
