Solvothermal synthesis, crystal structure and photoluminiscence of Cd(II) coordination polymer derived from a 1,2,3-triazole-based tricarboxylate ligand [Articol]

Abstract

A new polymeric complex of cadmium(II) was synthesized under solvothermal conditions by the reaction of 5-(4-carboxy-5-methyl-1H-1,2,3-triazol-1-yl) isophthalic acid (H3L) with cadmium nitrate tetrahydrate in a mixture of N,N-dimethylacetamide and water. The obtained compound was investigated using single crystal X-ray diffraction, thermogravimetry, infrared and photoluminescence spectroscopies. The polymeric complex obtained is an infinite 2D coordination polymer with the general formula {[Cd3L2(H2O)6]·2H2O}n (1). The intense photoluminescence emission of cadmium (II) complex was observed in the blue-violet region of the spectrum.
