title: Aqua-(3-hydroxy-benzoato-κO)bis-(1,10-phenanthroline-κN,N')cobalt(II) 3-hydroxy-benzoate penta-hydrate.
abstract: The crystal structure of the title compound, [Co(C(7)H(5)O(3))(C(12)H(8)N(2))(2)(H(2)O)](C(7)H(5)O(3))·5H(2)O, consists of Co(II) complex cations, uncoordinated hydroxy-benzoate anions and uncoord-inated water mol-ecules. The Co(II) ion is coordinated by two phenanthroline ligands, a water mol-ecule and a 3-hydroxy-benzoate anion, and displays a distorted octa-hedral geometry. π-π 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.
