Polybromide salts of tetraalkyl and N-heterocyclic cations: New entries into the structural library

Abstract

© 2017 Elsevier B.V. Reactions between Br2 dissolved in HBr and salts of various organic cations resulted in formation of a series of polyhalide salts: (IsoquinolH)Br3 (1), (2-BrPyH)Br3 (2), (H2(4,4′-bipy))(Br3)2 (3), Bu4NBr3 (4), (Collidinium){(Br3)(Br2)} (5) and Et4N{(Br3)(Br2)2} (6). All compounds were characterized by X-ray diffractometry; the role of supramolecular Br⋯Br contacts is discussed.
