Mass spectrometric and matrix isolation i.r. studies on the vaporisation of solid chromium(III) chloride over the temperature range 550-800 deg C reveal three different molecular chromium halides.At the lowest temperatures, CrCl4 is identified as the most volatile species and its tetrahedral structure confirmed by isotope patterns.At ca. 600 deg C, a new molecular species, CrCl3, appears and its structure is similarly shown to be planar (D3h).Further heating to ca. 780 deg C results in the formation of molecular CrCl2.The results are discussed in the light of previous studies on transition metal halide systems.
