Abstract: In the course of slow oxidation, the blue solution of TiCl₃ • 3THF in tetrahydrofuran turns from violet to yellow-brown and orange-re d as a consequence of the formation of mixed oxidation-state Ti(III,IV) compounds. On the basis of absorption and diffuse reflectance spectra in ultraviolet and visible regions, as well as absorption spectra in infrared region, it can be assumed that TiCl₃ • 2THF and TiCl₃ • 2THF • C₆H₆ have trigonal-bipyramidal configuration. The molecule of benzene in the complex TiCl₃ • 2THF • C₆H₆  is not a component of the coordination sphere of Ti(III) atom. The compound TiCl₃ • THF is a coordination polymer
