Abstract

© 2019, Pleiades Publishing, Ltd. By the reaction of a [BiX6]3− solution in HBr with the bromide salt of bis-(3-methyl-1-pyridino)ethane ((3-MePy)2C2Br2) the bromobismuthate complex ((3-MePy)2C2)4[Bi2Br11][BiBr6] (1) is obtained, which, when kept in the Br2 solution in HBr, transforms into ((3-MePy)2C2)3 [Bi2Br11](Br3) (2). Compounds 1 and 2 are characterized by single crystal XRD.
