Hybrid salts of binuclear Bi(III) halide complexes with 1,2-bis(pyridinium)ethane cation: Synthesis, structure and luminescent behavior

Abstract

Reactions between 1,2-bis(pyridinium)ethane bromide ((BPE)Br2) and [BiCl6]3-/[BiBr6]3- in HCl or HBr results in isostructural binuclear complexes (BPE)2[Bi2X10] (X = Cl (1) and Br (2)) which were characterized by X-ray diffractometry, IR and Raman spectroscopy. Both complexes manifest orange-red luminescence in solid state.
