The title compound, [Zn(C8H6O3)2(C12H12N2)]n, consists of [Zn(Hopa)2] (H2opa = 2-hydroxy-2-phenylacetic acid or mandelic acid) units bridged by 1,2-di-4-pyridylethane (bpe) ligands, forming a polymeric chain developing parallel to the b axis. The bridging bpe ligand is arranged around a twofold axis passing through the middle of the ethane C-C bond. The geometry around the ZnII ion is distorted octahedral, constructed by four O atoms from two Hopa- ligands and two N atoms from two bridging bpe ligands. O-HO hydrogen bonds link the chains, forming a three-dimensional network.
