Dalton communications. A convenient high-yield synthesis of some titanium( IV ) oxo cluster compounds: crystal structure of [Ti 3 Cl 3 (µ-O 2 CC 6 H 4 Me-p) 5 (µ-O)(µ 3 -O)]

The reaction of TiCl4 with a series of para-substituted benzoic acids (p-XC6H4CO2H; X = Me, Et, F or I) yields the new trinuclear oxo clusters [Ti3Cl3(µ-O2CC6H4X-p)5(µ-O)(µ3-O)] in good yield; p-ButC6H4CO2H gives [{[TiCl(O2CR)2]2O}n] but p-MeOC6H4CO2H yields only a black intractable tar.
