Bromine-rich complexes of bismuth: experimental and theoretical studies

Three novel polybromide complexes of bismuth(iii) – (2,6-MePyH)₃[BiBr₅(Br₃)] (1), (H₂bpp){[BiBr₅](Br₂)} (2) and (3-ClPyH)₂{[BiBr₅](Br₂)} (3) – were synthesized.

Bi(iii) polybromides: a new chapter in coordination chemistry of bismuth

A new family of bismuth coordination compounds – Bi(iii) polybromides – is introduced.

Halobismuthates with halopyridinium cations: appearance or non-appearance of unusual colouring

A series of chloro- and bromobismuthate complexes with bromopyridinium cations were prepared and characterized by XRD analysis and diffuse reflectance spectroscopy.

Heterogeneous bromination of alkenes using Bi(iii) polybromide complexes as {Br2} source

A new polybromide Bi(iii) complex (PyH)₃{[Bi₂Br₉](Br₂)} was synthesized, characterized by XRD, and used for selective bromination of alkenes.

Memory devices based on novel alkyl viologen halobismuthate(iii) complexes

Four novel halobismuthate(iii) complexes with alkyl viologen cations: (R2Viol)2[Bi2X10] (R = n-butyl, n-pentyl, X = Cl, Br) have been synthesized. Both chloride complexes revealed photochromic behavior and were successfully utilized for the fabrication of OFET-based memory devices with high switching coefficients and good write-read-erase cycling stability.
