Abstract
The crystals of the cluster [Li8Ti10F36O4(C5Me5)4(thf)8] 3 were isolated as the product of hydrolysis of [{(C5Me5)TiF3}4(LiF)2(thf)2] 2. The metal atoms in the cluster are six-coordinate (Ti and Li), or four-coordinate (Li). The oxido ligands form unsymmetrical oxido bridges Ti=O–Ti with a double-bond character. The mechanism of the cluster formation is proposed.
