Crystal structure of 2-methyl-1H-imidazol-3-ium aqua­tri­chlorido­(oxalato-κ(2) O,O′)stannate(IV)

The tin(IV) atom in the complex anion of the title salt, (C(4)H(7)N(2))[Sn(C(2)O(4))Cl(3)(H(2)O)], is in a distorted octa­hedral coordination environment defined by three chlorido ligands, an oxygen atom from a water mol­ecule and two oxygen atoms from a chelating oxalate anion. The organic cation is linked through a bifurcated N—H⋯O hydrogen bond to the free oxygen atoms of the oxalate ligand of the complex [Sn(H(2)O)Cl(3)(C(2)O(4))](−) anion. Neighbouring stannate(IV) anions are linked through O—H⋯O hydrogen bonds involving the water mol­ecule and the two non-coordinating oxalate oxygen atoms. In combination with additional N—H⋯Cl hydrogen bonds between cations and anions, a three-dimensional network is spanned.
