Syntheses, Crystal Structures and Photoluminescent Properties of Two New 1-D d10 Metal Complexes Based on Tetrazole 1-Acetato Ligand

摘要

Two new tetrazole 1-acetato complexes, [Ag(1-tza)(phen)]_∞(1) and [Cd(1-tza)2(2,2?-bipy)]∞(2)(1-Htza = tetrazole 1-acetato, phen = 1,10-phenanthroline, 2,2?-bipy = 2,2?-bipyridine), have been synthesized by solvothermal synthesis and structurally characterized by elemental analyses, IR spectra and single-crystal X-ray diffraction. Complex 1 shows a 1-D chained structure, while the structure of 2 contains two 1-D chains, which is the first 1-tza-based complex containing three different coordination modes of the 1-tza ligand. The aromatic stacking effects play an important role in the formation of supramolecular frameworks of these two complexes. Photoluminescent studies show that the two complexes exhibit efficient luminescence. In addition, optical diffuse reflectance spectra and thermogravimetric analyses of 1 and 2 have also been investigated.
