Synthetic Studies and Structural Aspects of some Metallacyclic Derivatives of Titanium (IV) - Better Precursors for Titania

Abstract

Titanium(IV) complexes of the type [(acac)2Ti(O-G-O] and [(acac)2Ti(OCH2CH2SH)2] {where G = (CH2)2, CH2CH(CH3), CH2CH(C2H5), CH(CH3)CH(CH3) have been synthesized in high yield by the interaction of the precursor [(acac)2Ti( OR)2] {where R = Pri , Et} with a variety of glycols and thioglycols in 1:1 and 1:2 molar ratios in refluxing benzene under anhydrous condition yield heteroleptic derivatives. On the basis of physico-chemical analyses, a cis-octahedral environment around Ti (IV) is proposed.

“…OH HO spectra [8,16,18]. The appearance of a couple of peaks in the range 2931-2849 cm -1 is due to the presence of alkoxyalkanol moiety in the complexes.…”

“…IR Spectra [14][15][16] : IR spectral bands of these pure compounds were assigned by comparing with the spectra of free ligands. A medium intensity band at 3450 cm -1 in the free ligands due to ν(OH) is absent in the spectra of all these complexes, indicating deprotonation of the alkoxyalkanols and the formation of metal-ligand bond through oxygen atom.…”
