A crystal‐field study of the ESR and UV spectra in relation to the structure of complexes of titanium(III) with chlorine and acetonitrile

Abstract

IFrom the ESR and W spectra the complex TiCI,(CH,CN), is shown, by means of the crystal-field theory, to have the configuration with Czv symmetry rather than that with C,, symmetry. The ESR and W spectra of the ion [TiCI,(CH,CN),]+, formed by adding a chlorine ion acceptor (e.g. TiCI,, SnCI,, AICI,, FeCI,) to a solution of anhydrous TiCI, in acetonitrile, could be calculated from the crystal-field parameters, which were determined from the spectra of TiCI, (CH,CN)
