PREPARATION AND OPTICAL AND ELECTRON SPIN RESONANCE SPECTRA OF SOME CHLORO(METHANOL) COMPLEXES OF TITANIUM(3)

Several new chloro complexes of titanium (III) have been isolated: H[TiCl4(C4H10O)], TiCl3(CH3OH)3, (C5H6N)TiCl4, (C5H6N)[TiCl4(CH3OH)2], and (C5H6N)2[TiCl5(CH3OH)]. These new compounds have been characterized and magnetic susceptibilities and optical Spectra are reported. Esr spectra have been determined for these and previously reported1 compounds of similar types. Three of the complexes, [TiCl(CH3OH)5]CL2, TiCl3(CH3OH)3, and (C5H6N)2[TiCl5(CH3OH)2], exhibited axial symmetry. No esr signals could be observed for the hexachlorotitanate(III), for the octachlorotitanate(III), or for (C5H6N)2[TiCl5(CH3OH)]. Three distinct g’s were observed for the other compounds. The nature of species present in methanol solutions of titamum(III) is discussed as are the electronic spectra of such species. © 1969, American Chemical Society. All rights reserved.
