Catena-Poly[[bis-(2-hydroxy-2-phenylacetato-2O 1,O2)zinc(II)] - 1,2-di-4-pyridylethane-2 N:N′]

Abstract

The title compound, [Zn(C8H6O3) 2(C12H12N2)] n, consists of [Zn(Hopa)2] (H2opa = 2-hydr-oxy-2-phenyl-acetic 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 octa-hedral, constructed by four O atoms from two Hopa- ligands and two N atoms from two bridging bpe ligands. O - H⋯O hydrogen bonds link the chains, forming a three-dimensional network. © Yu et al. 2009.
