Аннотация

Reaction of Cp ₂ TiCl ₂ (Cp = η ⁵ -C ₅ H ₅ ) with sodium 3,6-di-tert-butylcatecholate (Na ₂ Cat ³⁶ ) leads to mononuclear complex [Cp ₂ TiCat ³⁶ ], while the isomeric sodium 3,5-di-tert-butylcatecholate (Na ₂ Cat ³⁵ ) gives the mixed-valence binuclear complex [Cp ₂ Ti(μ-Cat ³⁵ ) ₂ TiCp]. The latter was characterized by EPR spectroscopy and magnetic susceptibility measurements, and shown to be a Ti-centred radical. DFT calculations confirm that the unpaired electron is located on the Ti atom from the TiCp ₂ fragment.
