The polymeric title compound, Ce(C(7)H(3)N(2)O(6))(3)(C(2)H(6)OS)(2), exists as a linear chain along [111] as the three dinitro-benzoate anions each engages in bridging adjacent dimethyl sulfoxide (DMSO) coordinated Ce(III) atoms. The metal atoms are surrounded by eight O atoms in a square-anti-prismatic environment. There are two independent formula units in the asymmetric unit. The S atoms of two of the four DMSO mol-ecules are disordered in a 0.926 (3):0.074 (3) ratio.
聚合标题化合物[Ce(C₇H₃N₂O₆)₃(C₂H₆OS)₂]ₙ以沿着[111]方向的线性链形式存在,因为三个二硝基苯甲酸根阴离子各自参与桥连相邻的二甲基亚砜(DMSO)配位的Ce(III)原子。金属原子在一个四方反棱柱环境中被八个O原子包围。不对称单元中有两个独立的化学式单元。四个DMSO分子中的两个的S原子以0.926 (3):0.074 (3)的比例无序排列。
