In the title compound, [Mn(C(7)H(2)F(3)O(3))(2)(C(10)H(8)N(2))(2)(H(2)O)(2)], the Mn(II) ion, situated on a centre of inversion, has a distorted octa-hedral coordination geometry and is coordinated by two N atoms from two 4,4'-bipyridine ligands, two O atoms from two 2,4,5-trifluoro-3-hy-droxy-benzoate ligands and two water mol-ecules. Inter-molecular O-H⋯N hydrogen bonds link the mol-ecules into a chain along the a axis. Inter-actions between neighboring chains occur through O-H⋯O hydrogen bonds, which link the chains into a two-dimensional supra-molecular network parallel to the ac plane. In addition, O-H⋯O hydrogen bonds between the water mol-ecules and carboxyl-ate groups also exist in the the crystal structure.
在标题化合物[Mn(C₇H₂F₃O₃)₂(C₁₀H₈N₂)₂(H₂O)₂]中,位于对称中心的Mn(II)离子具有扭曲的八面体配位几何构型,由两个4,4'-联吡啶配体的两个N原子、两个2,4,5-三氟-3-羟基苯甲酸酯配体的两个O原子和两个水分子配位。分子间的O—H⋯N氢键将分子沿a轴连接成链。相邻链之间通过O—H⋯O氢键发生相互作用,这些氢键将链连接成平行于ac平面的二维超分子网络。此外,晶体结构中水分子与羧酸根基团之间也存在O—H⋯O氢键。
