The crystal structure of the title compound, [Co(C(7)H(6)NO(2)S)(2)(H(2)O)(4)], is a polymorph of the structure first reported by Du, Zhao & Wang [(2004). Dalton Trans, pp. 2065-2072]. The asymmetric unit of the title compound contains one half-mol-ecule; the Co(II) atom lies on an inversion centre in a distorted octa-hedral geometry coordinated by two N atoms of the pyridine rings of the 4-pyridylthio-acetate anions and four O atoms of water mol-ecules. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules, forming a three-dimensional network.
标题化合物[Co(C₇H₆NO₂S)₂(H₂O)₄]的晶体结构是Du、Zhao和Wang首次报道的结构的一种多晶型物[(2004)。《道尔顿汇刊》，第2065 - 2072页]。标题化合物的不对称单元包含半个分子；Co(II)原子位于一个反演中心上，处于扭曲的八面体几何构型中，由4 - 吡啶硫代乙酸根阴离子的吡啶环的两个N原子和水分子的四个O原子配位。在晶体结构中，分子间的O - H⋯O氢键连接分子，形成三维网络。
