Bromobismuthates: Cation-induced structural diversity and Hirshfeld surface analysis of cation–anion contacts

Abstract

© 2017 Elsevier Ltd Reactions of [BiBr6]3−and bromide salts of various substituted pyridinium cations in excess of HBr result in a series of bromobismuthate anionic complexes of various geometry and nuclearity: [{BiBr4}n]n−, [Bi2Br9]3−and [Bi2Br10]4−. Hirshfeld surface analysis for 19 crystal structure was performed; impact of various X-Br contacts on the crystal structures is discussed.
