Abstract
In the title coordination polymer, [Zn(C7H6NO2)2(H2O)2]n, the ZnII cation is located on an inversion center and is coordinated by four pyridylacetate anions and two water molecules in a distorted ZnN2O4 octahedral geometry. The pyridine-N and carboxylate-O atoms of the pyridylacetate anion connect to two ZnII cations, forming a two-dimensional polymeric complex extending parallel to (212). Intermolecular O—H⋯O and weak C—H⋯O hydrogen bonding is present in the crystal structure.
