Abstract

In the title compound, Ni(C(9)H(4)O(6))(H(2)O)(3), the Ni(II) ion has a distorted NiO(5) square-pyramidal geometry, the maximum deviation from the least-squares plane formed by the basal atoms being 0.9351 (13) Å. The basal plane is formed by two O atoms from carboxyl-ate residues of the 5-carb-oxy-benzene-1,3-dicarboxyl-ate ligand and by two O atoms from water mol-ecules. The O atom of the third water mol-ecule is axially positioned, 1.7890 (19) Å perpendicular to the basal plane. The 5-carb-oxy-benzene-1,3-dicarboxyl-ate ligand bridges the metal atoms, forming a polymeric chain along the b axis. O-H⋯O hydrogen bonds between the water mol-ecules and carboxyl-ate groups stabilize the crystal structure.

摘要

在标题化合物[Ni(C₉H₄O₆)(H₂O)₃]ₙ中，Ni(II)离子具有扭曲的NiO₅四方锥几何构型，与由基底原子形成的最小二乘平面的最大偏差为0.9351(13) Å。基底平面由来自5-羧基苯-1,3-二羧酸酯配体羧酸盐残基的两个O原子和来自水分子的两个O原子形成。第三个水分子的O原子轴向定位，垂直于基底平面1.7890(19) Å。5-羧基苯-1,3-二羧酸酯配体桥接金属原子，沿b轴形成聚合物链。水分子与羧酸盐基团之间的O—H⋯O氢键稳定了晶体结构。
