Abstract
In the title complex, (CH(6)N(3))(2)[Zr(C(7)H(3)NO(4))(3)]·4H(2)O, the Zr(IV) ion lies on a twofold rotation axes and is coordinated by six O and three N atoms of three tridentate pyridine-2,6-dicarboxyl-ate ligands, forming a slightly distorted tricapped trigonal-prismatic geometry. In the crystal, O-H⋯O and N-H⋯O hydrogen bonds link the components into a three-dimensional network.
摘要
在标题配合物(CH₆N₃)₂[Zr(C₇H₃NO₄)₃]·4H₂O中，Zr(IV)离子位于二重旋转轴上，由三个三齿吡啶 - 2,6 - 二羧酸酯配体的六个O原子和三个N原子配位，形成略微扭曲的三帽三角棱柱几何构型。在晶体中，O—H⋯O和N—H⋯O氢键将各组分连接成三维网络。
