Three new Zn(II) coordination polymers with tetrazole-1-carboxylate ligand: Crystal structures and luminescent properties

The diversities of coordination modes of tetrazole-1-acetic (1-Htza) ligand lead to different structural networks of the three complexes: 1 with 1-D chained structure, 2 and 3 with 2-D (4,4)-connected framework. Photoluminescence studies show that the three complexes show strong luminescence, and the optical absorption spectra suggest complexes 1 and 3 possessing the wide gap semiconductor characters.
