Abstract
The title binuclear ZnII compound, [Zn2(C12H9O3)4(H2O)2], is centrosymmetric. Each Zn atom is coordinated by two bridging 2-naphthoxyacetate anions, one terminal 2-naphthoxyacetate anion and one water molecule in a distorted ZnO4 tetrahedral geometry. The naphthalene system of the bridging ligand is nearly perpendicular to the naphthalene of the terminal ligand, with a dihedral angle of 78.26 (6)°. Within the binuclear molecule the Zn⋯Zn separation is 3.815 (5) Å. In the crystal structure, intermolecular O—H⋯O hydrogen bonding between the water molecule and carboxylate groups helps to stabilize the crystal structure.
