Poly[(μ2-benzene-1,3-dicarboxylato-κ2O1:O3){μ2-1,2-bis[(1H-imidazol-1-yl)methyl]benzene-κ2N3:N3′}zinc]

Abstract

In the two-dimensional title coordination polymer, [Zn(C8H4O4)(C14H14N4)]n, the ZnII atom adopts a distorted tetrahedral geometry, being ligated by two O atoms from two different benzene-1,3-dicarboxylate dianions and two N atoms from two symmetry-related 1,2-bis(imidazol-1-ylmethyl)benzene molecules. The dihedral angles between the imidazole rings and the benzene ring in the neutral ligand are 76.31 (13) and 85.33 (15)°. The ZnII atoms are bridged by dicarboxylate ligands, forming chains parallel to the a axis, which are further linked by 1,2-bis(imidazol-1-ylmethyl)benzene molecules, generating a two-dimensional layer structure parallel to the ac plane. The crystal structure is enforced by intralayer and interlayer C—H...O hydrogen bonds.
