Abstract: The crystal structure of the title compound, [Co(C₇H₅O₃)(C₁₂H₈N₂)₂(H₂O)](C₇H₅O₃)·5H₂O, consists of Co^II complex cations, uncoordinated hydroxybenzoate anions and uncoordinated water molecules. The Co^II ion is coordinated by two phenanthroline ligands, a water molecule and a 3-hydroxybenzoate anion, and displays a distorted octahedral geometry. - stacking is observed between parallel phenanthroline ligands, the face-to-face separations being 3.454 (19) and 3.435 (7) Å. An extensive hydrogen-bonding network helps to stabilize the crystal structure. The hydroxybenzoate ligand is disordered over two positions, with site occupancy factors 0.6 and 0.4. One solvent water molecule is also disordered over two positions, with site occupancy factors 0.6 and 0.4.
