Tetraaquabis(2-{[5-(pyridin-4-yl)-1,3,4-oxadiazol-2-yl]sulfanyl}acetato)cobalt(II) monohydrate

Abstract

In the title compound, [Co(C9H6N3O3S)2(H2O)4]·H2O, the two 2-{[5-(pyridin-4-yl)-1,3,4-oxadiazol-2-yl]sulfan­yl}acetate ligands are monodentate. One coordinates the metal atom via the pyridyl N atom whereas the other coordinates via the carboxyl­ate O atom. The CoII atom adopts a slightly distorted octa­hedral coordination geometry with four O atoms of the coordinated water mol­ecules located in the equatorial plane and the N and O atoms of the two POA ligands in axial positions. In the crystal, the components are connected through O—H⋯O and O—H⋯N hydrogen bonds into a three-dimensional framework.
