Bis(triphenyltin) succinate exists as a centrosymmetric dinuclear molecule, [mu]-succinato-bis(triphenyltin), [Sn2(C4H4O4)(C6H5)6], with its Sn atom in tetrahedral coordination. When crystallized from an ethanol solution containing excess dimethyl sulfoxide (DMSO), it yields [[mu]-succinato-bis(triphenyltin)].[[mu]-succinato-bis(triphenyltin).sesqui(dimethyl sulfoxide).hemiethanol], [Sn4(C4H4O4)2(C6H5)12 (C2H6O)1/2(C2H6OS)3/2], and when crystallized from an ethanol solution containing excess hexamethylphosphoramide (HMPA), it yields [[mu]-succinato-bis(triphenyltin)].[[mu]-succinato- bis(triphenyltin).bis(hexamethylphosphoramide)], [Sn4(C4H4O4)2(C6H5)12(C6H18N3OP)2]. In the DMSO and HMPA complexes, the [[mu]-succinato-bis(triphenyltin)] moiety is carboxylate-bridged to the [[mu]-succinato-bis(triphenyltin).bis(donor)] moiety to give rise to a linear chain structure of tetranuclear complexes.
