Mono- and Binuclear Chloride and Bromide Complexes of Bi(III) with Double-Charged Cations Based on Pyridine: Syntheses and Crystal Structures

Abstract

The reactions of solutions obtained by the reactions of Bi₂O₃ with 2 M HCl and HBr with the salts containing bis(pyridyl)alkane cations afford mono- and binuclear halide complexes (Py-(CH₂)₃-Py)₃[Bi₂Br₉]₂ (I), (H₃O)(Py-(CH₂)₄-Py)[BiCl₆] ⋅ 3H₂O (II), and (H₂Bpp)₂[Bi₂Br₁₀] ⋅ 2H₂O (Bpp is 1,3-bis(4-pyridyl)propane) (III). The structures of the synthesized compounds are determined by X-ray diffraction analysis (СIF files CCDC no. 1583338–1583340, respectively).
