Abstract

The title compound, [Co(C7H4FO2)(2)(C6H6N2O)(2)(H2O)(2)], is a three-dimensional hydrogen-bonded supramolecular complex. The Co-II ion resides on a centre of symmetry and is in an octahedral coordination environment comprising two pyridyl N atoms, two carboxylate O atoms and two O atoms from water molecules. Intermolecular N-H...O and OH...O hydrogen bonds produce R-3(2)(6), R-2(2)(12) and R-2(2)(16) rings, which lead to two-dimensional chains. An extensive three-dimensional network of C-H...F, N-H...O and OH...O hydrogen bonds and pi-pi interactions are responsible for crystal stabilization.
