Poly[(μ(2)-benzene-1,3-dicarboxyl-ato-κ(2)O(1):O(3)){μ(2)-1,2-bis-[(1H-imidazol-1-yl)meth-yl]benzene-κ(2)N(3):N(3')}zinc].
In the two-dimensional title coordination polymer, [Zn(C(8)H(4)O(4))(C(14)H(14)N(4))](n), the Zn(II) atom adopts a distorted tetra-hedral geometry, being ligated by two O atoms from two different benzene-1,3-dicarboxyl-ate dianions and two N atoms from two symmetry-related 1,2-bis-(imidazol-1-ylmeth-yl)benzene mol-ecules. The dihedral angles between the imidazole rings and the benzene ring in the neutral ligand are 76.31 (13) and 85.33 (15)°. The Zn(II) atoms are bridged by dicarboxyl-ate ligands, forming chains parallel to the a axis, which are further linked by 1,2-bis-(imidazol-1-ylmeth-yl)benzene mol-ecules, generating a two-dimensional layer structure parallel to the ac plane. The crystal structure is enforced by intra-layer and inter-layer C-H⋯O hydrogen bonds.
