【 摘 要 】

In the previously reported [C2O4(SnPh3)2] complex [Diop et al. (2003). Appl. Organomet. Chem. 17, 881–882.], the SnIV atoms are able to formally complete their coordination by addition of dimethyl sulfoxide (DMSO) mol­ecules provided by the reaction medium, affording the title complex, [Sn2(C6H5)6(C2O4)(C2H6OS)2]. The SnIV atoms are then penta­coordinated, with a common trans trigonal–bipyramidal arrangement. The asymmetric unit contains one half-mol­ecule, which is completed by inversion symmetry in space group type C2/c. The inversion centre is placed at the mid-point of the central bis-monodentate oxalate dianion, C2O42−, which bridges the [(SnPh3)(DMSO)] moieties. The mol­ecule crystallizes as a disordered system, with two phenyl rings disordered by rotation about their Sn—C bonds, while the DMSO mol­ecule is split over two positions due to a tetra­hedral inversion at the S atom. All disordered parts were refined with occupancies fixed of 0.5.
