Crystal structure of bis­(2-methyl-1H-imidazol-3-ium) μ-oxalato-bis­[n-butyl­tri­chlorido­stannate(IV)]

The Sn(IV) atom in the centrosymmetric anion of the title salt, (C(4)H(7)N(2))(2)[Sn(2)(C(4)H(9))(2)(C(2)O(4))Cl(6)], is coordinated in a distorted octa­hedral mode by two O atoms of a bridging oxalate moiety, three Cl atoms and a C atom of an n-butyl group. The latter is disordered over two sets of sites in a 0.66:0.33 occupancy ratio. N—H⋯O and N—H⋯Cl hydrogen bonds involving the 2-methyl­imidazolium cation and neighbouring anions result in the formation of chains extending parallel to [001].
