Abstract: By the hydrothermal method, a four-coordinate monomeric CoII complex with two isonicotinate (C6H4NO2) ligands, [Co(L)2(H2O)2]·2H2O, where HL is isonicotinic acid, has been synthesized; it has been characterized by elemental analysis and X-ray diffraction techniques. The crystal structure reveals that the CoII atom, on an inversion center, has a CoN2O2 square-planar primary coordination environment and weak axial interactions with two more water molecules. Isonicotinate is bonded through nitrogen. A striking structural feature is the formation of a three-dimensional supramolecular architecture through intermolecular O-H
O hydrogen bonds.
