The crystal-structure analyses of the complexes [AlCl3(RNO2)] (R = Me or Ph) and NMR data in solution suggest a stronger Al-O co-ordinative interaction in the case of nitrobenzene compared to nitromethane; this could account for the dramatic solvent effects observed during certain electrophilic acylation processes involving AlCl3 as a promoter.
