Complexes formed by titanium(III) iodide

Abstract

Titanium(III) iodide has been allowed to react with a range of ligands containing oxygen and nitrogen donor atoms, and the complexes of the following stoicheiometry isolated and characterised: 2Til₃,3bipy, Til₃,2L (L = ethyleneglycol dimethyl ether, trimethylamine, α-picoline, and 1,10-phenanthroline), Til₃,3L (L = pyridine, γ-picoline, tetrahydrofuran, and 1,4-dioxan), and Til₃,4CH₃CN. Structures have been assigned to the compounds on the basis of various physical measurements, including conductivities and infrared spectra. The significance of the electronic spectra are discussed, and Dq for l^– estimated at 500–600 cm.^–1 with respect to titanium(III).
