In the title compound, [Mn(C(9)H(6)N(3)O(2))(2)(H(2)O)(4)]·10H(2)O, the Mn(II) ion is coordinated by two N atoms from two 4-(4H-1,2,4-triazol-4-yl)benzoate ligands and four water mol-ecules in a distorted octa-hedral geometry. The Mn(II) ion and two coordinated water mol-ecules lie on a twofold rotation axis. The water mol-ecules are involved in O-H⋯N and O-H⋯O hydrogen bonds with the triazole N atoms and carboxyl-ate O atoms, yielding a three-dimensional supra-molecular network. π-π inter-actions between the benzene rings [centroid-centroid distance = 3.836 (9) Å] are observed.
在标题化合物[Mn(C₉H₆N₃O₂)₂(H₂O)₄]·10H₂O中，Mn(II)离子由来自两个4-(4H-1,2,4-三唑-4-基)苯甲酸酯配体的两个N原子和四个水分子以扭曲的八面体几何构型配位。Mn(II)离子和两个配位水分子位于一个二重旋转轴上。水分子与三唑N原子和羧酸盐O原子形成O—H⋯N和O—H⋯O氢键，形成三维超分子网络。观察到苯环之间的π-π相互作用[质心-质心距离 = 3.836 (9) Å]。
