Mixed aluminium chloro/fluoro anions are formed in dichloromethane solution by the interaction of AlCl3 and .Aluminium-27 n.m.r. studies are restricted to the stoichiometric ranges F/Al from 1:1 to 3:1 and F/Al>8:1.Between these limits rapid precipitation reactions occur.In the Fluoride-rich stoichiometric range there is rapid exchange on the n.m.r. time scale between the aluminium fluoro anion and free fluoride, so that a direct identification of the species by the multiplicity of the resonance is not possible.Indirect evidence strongly suggests that the aluminium species is -.In the F/Al stoichiometry range from 1:1 to 3:1 aluminium-27 resonances were observed for all the other possible - species.Studies on the aluminium iodo/fluoro system support the identification of -, but the system is labile and the mixed iodo/fluoro species undergo rapid disproportionation.
