In the complex cation of the title compound, Zn(C(17)H(13)N(2)O(2))(2)(H(2)O)(4)(2)·2.5H(2)O, the Zn(II) atom, lying on an inversion center, is coordinated by two N atoms from two N-(3-carb-oxy-phen-yl)-4,4'-bipyridin-1-ium ligands and four water mol-ecules in a distorted octa-hedral geometry. The pyromellitate anion is double deprotonated. O-H⋯O and C-H⋯O hydrogen bonds connect the cations, anions and uncoordinated water mol-ecules into a three-dimensional supra-molecular network. One of the two lattice water molecules shows an occupancy of 0.25. An intra-molecular O-H⋯O hydrogen bond is present in the anion.
在标题化合物Zn(C₁₇H₁₃N₂O₂)₂(H₂O)₄₂·2.5H₂O的络合阳离子中,位于对称中心的Zn(II)原子由来自两个N-(3-羧基苯基)-4,4'-联吡啶-1-鎓配体的两个N原子和四个水分子以扭曲的八面体几何构型配位。均苯四甲酸根阴离子是双去质子化的。O-H⋯O和C-H⋯O氢键将阳离子、阴离子和未配位的水分子连接成三维超分子网络。两个晶格水分子中的一个占有率为0.25。阴离子中存在分子内O-H⋯O氢键。
