Two triazole-based coordination polymers: Synthesis and crystal structure characterization

Here we reported two new triazole-based coordination polymers (CPs), i.e., [Zn(Hdatrz)(μ 2-O)] n (1) together with [Mn(Hdatrz)(C2O4)] n ·n(H2O) (2) (Hdatrz = 3,5-diamino-1,2,4-triazole), which were generated under solvothermal conditions. The influence of different metal ions on the structure and properties of CPs was investigated. The CPs’ whole structures have been completely characterized by the powder X-ray diffraction, Fourier transform infrared spectroscopy, and thermogravimetric analysis. It is noteworthy that, upon excitation at 390 nm, ligands of compounds 1 and 2, as well as the metal complexes, all exhibit luminescence at 432 nm.
