(5,5′-Dimethyl-2,2′-bipyridine-κ(2) N,N′)(1-naphthyl­acetato-κO)(1-naphthyl­acetato-κ(2) O,O′)zinc hemihydrate

In the title compound, [Zn(C(12)H(9)O(2))(2)(C(12)H(12)N(2))]·0.5H(2)O, the water mol­ecule lies on a twofold rotation axis. The Zn(II) atom is coordinated by three O atoms from two 1-naphthyl­acetate ligands, one monodentate and the other asymmetric bidentate chelate, and two N atoms from a 5,5′-dimethyl-2,2′-bipyridine ligand, giving an irregular environment. In the crystal, the complex mol­ecules are inter­linked through the water mol­ecule by O—H⋯O(carboxyl­ate) hydrogen bonds, together with weak C—H⋯O and bipyridine ring π–π stacking inter­actions [ring centroid separation = 3.761 (2) Å], giving a two-dimensional network structure.
