Carbonylation of Ti(η-C4H6)2(dmpe)[dmpe = 1,2-bis(dimethylphosphino)ethane] or reduction of TiCl4.2THF in the presence of dmpe and CO affords [Ti(CO)3(dmpe)3/2]n which reacts wih PF3 and dmpe to form Ti(CO)2(PF3)(dmpe)2, [a derivative of the non-existent Ti(CO)7], the X-ray crystal structure of which is reported.
