In the structure of the title compound, [Mg(C7H3N2O6)2(H2O)4]·4H2O, the slightly distorted octa-hedral MgO6 coord-in-ation polyhedron comprises two trans-related carboxyl-ate O-atom donors from mononodentate 3,5-dinitro-benzoate ligands, and four water mol-ecules. The coordinating water mol-ecules and the four water mol-ecules of solvation give both intra- and inter-unit O-H⋯O hydrogen-bonding inter-actions with carboxyl-ate, water and nitro O-atom acceptors, forming a three-dimensional structure.
在标题化合物[Mg(C₇H₃N₂O₆)₂(H₂O)₄]·4H₂O的结构中，稍有畸变的八面体MgO₆配位多面体包含来自单齿3,5-二硝基苯甲酸酯配体的两个反式相关的羧酸根O原子供体，以及四个水分子。配位水分子和四个溶剂化水分子与羧酸根、水和硝基O原子受体形成单元内和单元间的O—H⋯O氢键相互作用，形成三维结构。
