Abstract

In the centrosymmetric title complex, [Ni(C(7)H(6)NO(2)S)(2)(H(2)O)(4)], the Ni(II) atom, located on a centre of inversion, is coordinated by two N atoms from two 2-(4-pyridyl-sulfan-yl)acetate ligands and four water O atoms in an octa-hedral geometry. In the crystal, inter-molecular O-H⋯O hydrogen bonds between the coordinated water mol-ecules and the carboxyl-ate group of the anionic 2-(4-pyridyl-sulfan-yl)acetate ligands link these discrete mononuclear units into a three-dimensional network.

摘要

在中心对称的标题配合物[Ni(C₇H₆NO₂S)₂(H₂O)₄]中，位于对称中心的Ni(II)原子由来自两个2-(4-吡啶基硫烷基)乙酸酯配体的两个N原子和四个水分子的O原子以八面体几何构型配位。在晶体中，配位水分子与阴离子2-(4-吡啶基硫烷基)乙酸酯配体的羧酸根基团之间的分子间O—H⋯O氢键将这些离散的单核单元连接成三维网络。
