Abstract

Abstract

A new coordination polymer, namely, {[Zn(DTPP)(H2O)2]·H2O}n (H2DTPP = 3-(3,5-di(2H-tetrazol-5-yl)phenoxy)pyridine, compound 1), was successfully assembled by using a new semirigid tripodal nitrogen-containing heterotopic ligand and characterized by single-crystal X-ray diffraction, elemental analysis, infrared spectroscopy, TG, and luminescence. X-ray single-crystal diffraction analysis revealed that compound 1 crystallizes in an orthorhombic crystal system with space groups of Ibca. It is a 2D coordination network with (4·82) topology, and the 2D networks are further connected by hydrogen bonds between coordinated water molecules and tetrzolyl N atoms to form a 3D supramolecular framework. Moreover, compound 1 exhibits intense blue emission centered at 345 nm upon excitation at 276 nm and has the ability to sense Fe3+ via photoluminescence quenching.
