Zinc(II) coordination architectures based on 5-(1H-tetrazol-1-yl)-isophthalic acid: Synthesis, structures and luminescent properties

With different pyridine-analogs as auxiliary ligands, three novel Zn(II) complexes (1–3) based on 5-(1H-tetrazol-1-yl) isophthalic acid (H2L) have been synthesized and structurally characterized. Single crystal X-ray diffraction analyses of complexes 1–3 show the presence of tetrazolyl group, as well as the coordination behavior of the auxiliary ligands as critical factors determining the structures of such Zn(II)-carboxylate coordination architectures. In addition, the resulting complexes all exhibit luminescence properties in the solid state at room temperature.
