The six-coordinate Sn atom in bis , exists in a cis±C 2 SnO 4 coordination sphere [SnÐC 2.127 (5) A Ê ; CÐSnÐC 109.2 (3) ]. The anion lies on a special position of 2 symmetry. The ammonium cations and the stannate anions are linked by hydrogen bonds into a linear chain.
The title compound, 2 C 2 H 8 N + ÁC 12 H 8 O 4 2À , crystallizes as a salt in space group P2 1 /n, the anion being located on an inversion center. The dimethylammonium cations link neighboring carboxylate anions via two N + ÐHÁ Á ÁO hydrogen bonds [HÁ Á ÁO = 1.72 (3) and 1.84 (3) A Ê , NÁ Á ÁO = 2.
