Preparation and characterization of carboxylato derivatives of bis-(methyl cyclopentadienyl) titanium(IV)

Dicarboxylato complexes of bis-(methyl cyclopentadienyl) titanium(IV), of the type (CH 3 C 5 H 4 ) 2 TiA 2 (A = CH 3 COO, CH 3 CH 2 COO, CH 3 CH 2 CH 2 COO, C 6 H 5 COO, CH 2 ClCOO or CHCl 2 COO), have been prepared in aqueous as well as in nonaqueous medium, by the reaction of bis-(methyl cyclopentadienyl) titanium dichloride on appropriate sodium salt of the carboxylic acid. The carboxylato ligand is chelating and the carboxylato compounds are non electrolytic in nature. The bonding of carboxylato ligand in these complexes has been discussed and these complexes have been characterized by elemental analysis m.p. conductivity measurement and IR and NMR spectral studies.
