title: Bis(μ-6-hydroxy-naphthalene-1-carboxyl-ato)bis-[(6-hydroxy-naphthalene-1-car-box-yl-ato)(1,10-phenanthroline)cadmium(II)] tetra-hydrate.
abstract: The title complex, [Cd(2)(C(11)H(7)O(3))(4)(C(12)H(8)N(2))(2)]·4H(2)O, has a centrosymmetric binuclear structure in which two Cd(II) atoms are both six-coordinated and bridged by 6-hydroxy-naphthalene-1-carboxyl-ate ligands, with a Cd⋯Cd separation of 3.671 (1) Å. The remaining coordination sites are occupied by two N atoms of a 1,10-phenanthroline ligand and two O atoms of a 6-hydroxy-naphthalene-1-carboxyl-ate ligand. The crystal packing is stabilized by O-H⋯O hydrogen-bonding inter-actions.
