catena-Poly[[(acetato-κO)[4-(1H-pyrazol-3-yl)pyridine-κN]zinc]-µ-acetato-κO:O'].

In the title compound, [Zn(CH(3)CO(2))(2)(C(8)H(7)N(3))](n), the Zn(II) atom is coordinated by one N atom from a 4-(1H-pyrazol-3-yl)pyridine ligand and three O atoms from two bridging and one terminal acetate ligands, forming a distorted tetra-hedral geometry. The bridging acetate ligands link the Zn atoms into a chain along [001]. N-H⋯O hydrogen bonds and π-π inter-actions between the pyridine and pyrazole rings [centroid-centroid distance = 3.927 (3) Å] connect the chains into a layer parallel to (011).
