Abstract

In the title centrosymmetric complex, [Zn(C(7)H(5)N(2)O(4))(2)(H(2)O)(2)]·2H(2)O, the Zn(II) ion is coordinated in a trans mode by two symmetry-related bis-chelating 6-methoxycarbonyl-pyridazine-3-carboxyl-ate ligands via N and O atoms, and by two aqua ligand O atoms in axial positions, in a slightly distorted octa-hedral environment. In the crystal structure, complex mol-ecules are linked by inter-molecular O-H⋯O hydrogen bonds between coordinated and solvent water mol-ecules and carboxyl-ate O atoms, forming mol-ecular ribbons propagating along the a axis.

摘要

在标题中的中心对称配合物[Zn(C₇H₅N₂O₄)₂(H₂O)₂]·2H₂O中，Zn(II)离子通过两个对称相关的双螯合6 - 甲氧基羰基哒嗪 - 3 - 羧酸根配体经N和O原子以反式模式配位，并在轴向位置通过两个水配体的O原子配位，处于略微扭曲的八面体环境中。在晶体结构中，配合物分子通过配位水分子与溶剂水分子以及羧酸根O原子之间的分子间O—H⋯O氢键相连，形成沿a轴延伸的分子带。
