Bis[µ-2-(2-naphth-oxy)acetato]bis-{aqua[2-(2-naphth-oxy)acetato]zinc(II)}.

ABSTRACT

The title binuclear Zn(II) compound, [Zn(2)(C(12)H(9)O(3))(4)(H(2)O)(2)], is centrosymmetric. Each Zn atom is coordinated by two bridging 2-naphthoxyacetate anions, one terminal 2-naphth-oxy-acetate anion and one water mol-ecule in a distorted ZnO(4) tetra-hedral 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 mol-ecule the Zn⋯Zn separation is 3.815 (5) Å. In the crystal structure, inter-molecular O-H⋯O hydrogen bonding between the water mol-ecule and carboxyl-ate groups helps to stabilize the crystal structure.
