Diaqua(5-methylpyrazine-2-carboxylato-²N,O)cobalt(II)

G. Fan, S.-P. Chen and S.-L. Gao

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.
