The title compound, [Co(C(7)H(4)FO(2))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(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 O-H...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 O-H...O hydrogen bonds and pi-pi interactions are responsible for crystal stabilization.
