(5,5′-Dimethyl-2,2′-bipyridine-κ2N,N′)(1-naphthylacetato-κO)(1-naphthylacetato-κ2O,O′)zinc hemihydrate

In the title compound, [Zn(C12H9O2)2(C12H12N2)]·0.5H2O, the water molecule lies on a twofold rotation axis. The ZnII 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...Ocarboxylate 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.
