A 2-D tetrazole-based Zn(II) coordination polymer: crystal structure, dielectric constant, and luminescence

Abstract

A tetrazole-based Zn(II) coordination polymer, [Zn(TMPT)2] n (1) (TMPT = 5-(4-((1H-1,2,4-triazol-1-yl)methyl)phenyl)-2H-tetrazole), was synthesized by in situ reaction of 4-((1H-1,2,4-triazol-1-yl)methyl)benzonitrile, Zn(NO3)2 · 6H2O, and NaN3 under hydrothermal conditions and structurally characterized by single-crystal X-ray diffraction. Complex 1 contains π–π stacking interactions between tetrazole rings and phenyl rings of the 2-D ordered layered structural framework, which contribute to the dielectric response. In addition, 1 was demonstrated to display strong blue fluorescence emissions in the solid state at room temperature.
