The spectra and structure of aluminium chloride complexes. Part IV. Structure of higher complexes of aluminium chloride

Abstract

The complexes AlCl3,2Me2O,AlCl3,1·5MeCN, AlCl3,2MeCN, and AlCl31·5HCO2Me have been examined by i.r. and Raman spectroscopy; model calculations support a trigonal-bipyramidal five-co-ordinate structure for AlCl3,2Me2O but ionic structures are suggested for the others. AlCl3,2MeCN has uncombined MeCN in the crystal lattice.
