Diaqua(isonicotinamide-κN1)(4-methoxybenzoato-κ2O,O′)(4-methoxybenzoato-κO)cobalt(II)

In the title complex, [Co(C8H7O3) 2(C6H6N2O)(H2O) 2], the CoII atom is coordinated by three O atoms from two 4-methoxy-benzoate ligands, which act in different modes, viz. monodentate and bidentate, two water molecules and one N atom of the isonicotinamide ligand in a distorted octa-hedral geometry. The monodentate-coordinated carboxylate group is involved in an intra-molecular O-H⋯O hydrogen bond with the coordinated water molecule. In the crystal structure, inter-molecular O-H⋯O and N-H⋯O hydrogen bonds link the molecules into layers parallel to the ab plane. The crystal packing is further stabilized by weak C-H⋯O hydrogen bonds and π-π inter-actions indicated by the short distance of 3.6181 (8) Å between the centroids of the benzene and pyridine rings of neighbouring molecules.
