The Sn(IV) atom in the centrosymmetric anion of the title salt, (C4H7N2)2[Sn2(C4H9)2(C2O4)Cl6], is coordinated in a distorted octa-hedral 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-methyl-imidazolium cation and neighbouring anions result in the formation of chains extending parallel to [001].
标题盐((C_4H_7N_2)_2[Sn_2(C_4H_9)_2(C_2O_4)Cl_6])的中心对称阴离子中的(Sn(IV))原子,通过一个桥连草酸根部分的两个(O)原子、三个(Cl)原子和一个正丁基的(C)原子以扭曲的八面体模式配位。后者在两组位置上无序分布,占有率比为(0.66:0.33)。涉及(2 - 甲基咪唑鎓阳离子和相邻阴离子的(N - H⋯O)和(N - H⋯Cl)氢键导致形成平行于([001])延伸的链。
