The N-or P-coordinated complexes of monoalkyl carboxyl and sulfonyl titanate were prepared.By means of XPS the N→Ti or P→Ti coordination bonds in these complexes were ascertained,and the relative bonding strength were estimated from the magnitude of the chemical shift data.The sulfonyl titanates are easier to be coordinated with N or P ligands, than the carboxyl titanates;and the hydroxysubstituted amines were coordinated easily with titanates;The chemical shifts of P-coordinated complexes were not pronounced as in the com-plexes with N-ligands.It may be caused by the "back donation" of Ti→P in these complexes. In addition,The intra-molecular N→Ti coordinate linkage has also been identified in the reaction products of isopropyl titanate and ethyl hydroxyl amines.
