聚合物标题化合物,[Ce(C7H3N2O6)3(C2H6OS)2]n,作为直链沿着[111]存在,因为三个二硝基苯甲酸根阴离子各自参与桥接相邻的二甲亚砜(DMSO)配位的Ce III原子。在正方形反棱柱环境中,金属原子被八个氧原子包围。不对称单元中有两个独立的分子式单元。四个DMSO分子中的两个的S原子以0.926(3):0.074(3)的比例无序。  
The polymeric title compound, [Ce(C7H3N2O6)3(C2H6OS)2]n, exists as a linear chain along [111] as the three dinitrobenzoate anions each engages in bridging adjacent dimethyl sulfoxide (DMSO) coordinated CeIII atoms. The metal atoms are surrounded by eight O atoms in a square-antiprismatic environment. There are two independent formula units in the asymmetric unit. The S atoms of two of the four DMSO molecules are disordered in a 0.926 (3):0.074 (3) ratio.
