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.

In the title one-dimensional ZnIIcoordination polymer, [Zn(C10H8O4)0.5Cl(C12H12N6)]n, the asymmetric unit consists of a ZnIIcation, a 1,3-bis[(1H-1,2,4-triazol-1-yl)methyl]benzene ligand and half of a fully deprotonated centrosymmetric 1,4-phenylenediacetic acid ligand. The crystal structure shows a one-dimensional rotaxane-like structure. This coordination polymer is reinforced by C—H...O and C—H...Cl hydrogen bonds and π–π interactions.
