HMIM Br9 : a Room-temperature Ionic Liquid Based on a Polybromide Anion

Abstract: [HMIM][Br-9] ([HMIM] = 1-hexyl-3-methylimidazolium) has been investigated by Raman spectroscopy, single-crystal X-ray diffraction and NMR spectroscopy. Conductivity measurements show a high electrical conductivity like other polybromides
