Antimony(V) Bromide and Polybromide Complexes with N-alkylated Quinolinium or Isoquinolinium Cations: Substituent-dependent Assembly of Polymeric Frameworks

Abstract

© 2019 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim Reactions of [SbIIIBr6]3– with Br2 in HBr in the presence of N-substituted quinolinium or isoquinolinium cations result in new complexes of hexabromidoantimonates of SbV and their polybromide adducts: (N-MeQuin)2{[SbBr6](Br3)} (1), (N-MeIsoquin)2{[SbBr6](Br3)} (2), and (N-EtQuin)[SbBr6] (3). Thermal stability was studied; estimated energies of supramolecular Br···Br interactions were calculated.
