Some novel ternary and quaternary complexes of titanium(IV) of general formula [Ti(acac)Cl3−n(OOCR)n] (R = C15H31 or C17H35 and n = 1–3) have been synthesized by stepwise substitution of chloride ions of [Ti(acac)Cl3] by straight chain carboxylic acid anions. The complexes are characterized by their elemental analyses, spectral (infrared, FAB mass, 1H NMR and powder XRD) studies, molecular weight determination and molar conductance measurements. Infrared spectra suggested bidentate chelating nature of both acetylacetonate and carboxylate anions in the complexes. Monomeric nature of the complexes was confirmed by their molecular weight determination and FAB mass spectra. Molar conductance values indicated the complexes to be non-electrolytes in DMF. The complexes exhibited high resistance to hydrolysis. Their powder XRD data indicated the nano-size for the complexes. The coordination number of titanium(IV) in these complexes were found to be six, seven and eight which has been discussed in detail.
