Crystalline products were obtained when TiCl4 was reacted in dichloromethane with acetic, propionic, crotonic, benzoic, furoic and salicylic acids. Chemical analysis has shown that these were all dichlorodicarboxylatotitanium (Ⅳ). Cryoscopy of dichlorodipropionatotitanium (Ⅳ) indicated the carboxylato-complexes are dimeric. In the IR spectra of these complexes two strong bands both assigned to asymmetric carbonyl stretching vibration have been observed in the region 1500 - 1700cm-1 and the NMR spectrum of dichlorodipropionatotitanium (Ⅳ) has also shown two triplets and two quartets, which indicate that there are two chemically unequivalent carboxylato-ligands in the dimer [TiCl2(OOCR)2]2. Their molecular structure was proposed to be bis-carboxo-bridged dimer.
