title: Monoclinic polymorph of trans-tetra-aquabis-[(4-pyridylsulfanyl)-acetato-κN]cobalt(II).
abstract: 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.
