The structure arises from π–π stacking between the benzyl and tetrafluoropyridyl groups of the cations and cation–bromide interactions. It is the latter that gives rise to the non-centrosymmetry.application/pdfenThis is an author’s accepted version of an article published in the journal: CrystEngComm. © 2011 Royal Society of Chemistry.chemistryOn the importance of π–π stacking and cation–anion interactions in the construction of non-centrosymmetric networks of bromide salts of imidazolium cations bearing arene and polyfluoroarene ringsJournal Article10.1039/C1CE00003A
