Abstract: The title compound, [Co(C₇H₅O₃)₂(C₇H₅N₃O₂)₂(H₂O)₂]·2C₇H₅N₃O₂·2H₂O, is composed of neutral Co^II-containing complexes, accompanied by uncoordinated nitrobenzimidazole (Nbzim) molecules and water molecules. The Co^II atom is located on a twofold axis and coordinated by two Nbzim molecules, two 3-hydroxybenzoate anions and two water molecules in a slightly distorted octahedral geometry. The crystal packing is stabilized by extensive hydrogen bonding and - stacking between coordinated and uncoordinated Nbzim molecules.
