Gallium cations, solvation

Cationic Compiexes. Apart from the aqua ions and partially substituted species such as [GaCl(H20)5] +, cationic complexes of gallium halides with pyridine, bipyridine, or phenanthroline are known, for example, [GaCl2(phen)2]+ and [Ga(phen)3] +. Furthermore, given the steric hindrance about the gallium center in complexes formulated as GaX3(NH3) (X = Cl, n = 1, 3, 5, 6, 7, 14 X = Br, n = 1, 5, 7, 9, 14 X = I, n = 1, 5, 6, 7, 9, 13, 20), it is likely that where n is greater than 3 these are also cationic solvates.
