Poly[(mu(2)-benzene-1,3-dicarboxylato-kappa O-2(1):O-3){mu(2)-1,2-bis[(1H-imidazol-1-yl)-methyl]benzene-kappa N-2(3):N-3'}zinc]

In the two-dimensional title coordination polymer, [Zn(C8H4O4)(C14H14N4)] n, the Zn-II 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)degrees. The Zn-II 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 center dot center dot center dot O hydrogen bonds.
