title: Bis(μ-cyclo-hexane-1,4-dicarboxyl-ato)bis-{aqua-[1-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)naphthalen-2-ol]cadmium} monohydrate.
abstract: The asymmetric unit of the title compound, [Cd(2)(C(8)H(10)O(4))(2)(C(23)H(14)N(4)O)(2)(H(2)O)(2)]·H(2)O, consists of one half of the dimeric complex, which lies about an inversion centre, and a half-occupancy solvent water mol-ecule on a general position. Each Cd(II) cation is six-coordinated by the two N atoms from one 1-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)naphthalen-2-ol (L) ligand and three O atoms from two different 1,4-chdc(2-) ligands (1,4-H(2)chdc = cyclo-hexane-1,4-dicarb-oxy-lic acid), two coordinating in a bidentate fashion and the other in a monodentate fashion. The distorted octa-hedral coordination sphere is completed by a coordinated water mol-ecule. The Cd(II) atoms are each bridged by two 1,4-chdc(2-) ligands, forming an inversion dimer with the L ligands located on the outside of the dimeric unit. An intra-molecular N-H⋯O hydrogen bond occurs. In the crystal, O-H⋯O and N-H⋯O hydrogen-bonding inter-actions stabilize the packing.
