Abstract

The crystal structure of the title compound, [Co(C6H4NO2)(2)(H2O)(2)]center dot 2H(2)O, has been reinvestigated with improved precision [previous reports: Chang et al. (1972). J. Coord. Chem. 2, 31-34; Lumme et al. (1969). Suom. Kemistil. B, 42, 270]. In the title compound, the Co atom is located on an inversion center and its coordination can be described as slightly distorted octahedral, equatorially trans-coordinated by two N and O atoms of two picolinate ligands and axially coordinated by two O atoms of the water molecules. Intermolecular O-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen-bonding interactions result in the formation of an intricate three-dimensional network.
