X-Ray absorption spectroscopy investigation on the structure of methyl acrylate–TiCl4 complexes in solution

Abstract

EXAFS and XANES spectra of methyl acrylate–TiCl₄ complexes in nitrobenzene show that the titanium atom is coordinated to two oxygen atoms and four chlorine atoms for any methyl acrylate/TiCl₄ ratio; furthermore, there is no free TiCl₄, so some carbonyls must be coordinated to two titanium atoms, as confirmed by IR spectroscopy; coordination increases the titanium–chlorine distance with regard to TiCl₄.
