Abstract: In the title complex, [Co(C6H5N2O2)2(H2O)2], the Co2+ cation lies on an inversion centre and the coordination geometry is distorted octahedral, with two N atoms and two O atoms from the 5-methylpyrazine-2-carboxylate ligands in the equatorial plane. The two remaining coordination sites are occupied by two water molecules. The crystal structure is stabilized by a network of O-HO hydrogen-bonding interactions, forming a two-dimensional supramolecular structure.
