Bi(III) halide complexes containing 4,4′-vinylenedipyridinium cation: Synthesis, structure and luminescence in solid state

Binuclear Bi(III) halide complexes (H2bpen)2[Bi2X10] (X = Cl (1) and Br (2)) (bpen = 4,4′-vinylenedipyridine) have been synthesized and characterized by X-ray diffraction. Both complexes display blue–green luminescence.
