(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)]center dot 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 center dot center dot center dot O-carboxylate hydrogen bonds, together with weak C-H center dot center dot center dot O and bipyridine ring pi-pi stacking interactions [ring centroid separation = 3.761 (2) angstrom], giving a two-dimensional network structure.
