The title compound, [Co(C7H5O2)2(C6H 6N2O)2(H2O)2], is a crystallographically centrosymmetric monomeric complex in which pyridine N, and carboxylate and water O atoms form a tetragonally Jahn-Teller-distorted octahedron about the CoII ion, with bond distances of 2.150 (1), 2.085 (1) and 2.141 (1) A, respectively. There is a hydrogen bond between nicotinamide N and O atoms [N...O 2.976 (2) A], and the non-coordinated O atom of the carboxylate group and that of nicotin-amide form hydrogen bonds with water O atoms [O...O 2.580 (2) and 2.911 (1) A, respectively].
