Bis(4-hydroxy­benzoato-κO)bis­(1,10-phenanthroline-κ2N,N′)cadmium(II) dihydrate

In the title compound, [Cd(C7H5O3)2(C12H8N2)2]·2H2O, the CdII ion is located on a twofold axis and assumes a distorted octa­hedral CdN4O2 coordination geometry, formed by two phenanthroline (phen) ligands and two 4-hydroxy­benzoate (HBA) anions. π–π stacking is observed between the parallel phen ligands of adjacent CdII complexes. One water O atom is located on a twofold axis. The other water mol­ecule is disordered over two sites.
