Some volatile binary metal-organic frameworks of titanium (IV), [Ti(OOCR) 4 ] (where R = C 13 H 27, C 15 H 31, C 17 H 35 or C 21 H 43 ) were synthesized by the reaction of titanium tetrachloride and sodium salts of the straight chain fatty acids (prepared in situ) in 1:4 molar ratio. The isolated solid products were showing poor crystallinity and were characterized by their elemental analyses, molecular weight determinations, conductance, spectral (infrared, 1 H NMR, 13 C NMR, FAB mass and powder XRD) and TEM studies. Their monomeric nature was confirmed by molecular weight determinations and FAB mass spectra. Eight coordination number of titanium (IV) have been assigned in the isolated compounds. TEM indicated the particles are spherical in shape having ~200 nm diameter.
