A new dinuclear lead(II) complex of 2,3-diphenyl-tetrazole-5-thione: synthesis and characterization

摘要

The present work reports on the synthesis, crystalstructure, fluorescence, electrochemical behavior, andthermogravimetric analysis of a new dinuclear lead(II) complex of2,3-diphenyl-tetrazole-5-thione. Its structure was characterized byX-ray crystallography, IR spectroscopy, and elemental analysis. Eachlead atom adopts a distorted octahedral geometry by coordinating to 2sulfur atoms from 2 2,3-diphenyl-tetrazole-5-thione ligands and 4oxygen atoms from 3 nitrates. The fluorescence spectrum shows thatthe title complex has 2 fluorescence emission peaks, at 412 nm and 433nm. Cyclic voltammetry studies show that the title complex has onlyone reduction peak, at 0.309 V. The thermogravimetric analysisindicates that the title complex shows a thermal stability below 211°C; it may decompose instantly above that temperature.
