Abstract:
A series of octanuclear iodine-bromine interhalides [In Br8-n ]2- (n=0, 2, 3, 4) were prepared systematically in two steps. Firstly, addition of a dihalogen (Br2 or IBr) to the triaminocyclopropenium bromide salt [C3 (NEt2 )3 ]Br forms the corresponding trihalide salt with Br3 - or IBr2 - anions, respectively. Secondly, addition to Br3 - of half an equivalent of Br2 gives the octabromine polyhalide [Br8 ]2- , whereas addition to IBr2 - of half an equivalent of Br2 , IBr or I2 gives the corresponding interhalides: [I2 Br6 ]2- , [I3 Br5 ]2- , and [I4 Br4 ]2- , respectively. The four octahalides were characterized by X-ray crystallography, computational studies, Raman and Far-IR spectroscopies, as well as by TGA and melting point. All of the salts were found to be ionic liquids.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
