Abstract

A new 1-D Pb(II) complex {[Pb2(H2O)4(tppbc)2] · (CH3)2NCHO} n (1) based on tetrazole-carboxylate bifunctional ligand has been prepared and characterized (tppbc = 3-(4-(2-(1H-tetrazol-5-yl)phenyl-4-yl)phenyl)-2-ethoxy-3H-benzimidazole-4-carboxylic acid). Photo-luminescence measurements indicate that although the fluorescence of tppbc is quenched after coordination, the Pb(II) complex shows strong intense phosphorescence emission. Lifetimes at 298 K and low temperatures agree with the large Stokes shift of 1.
