Titanium: Inorganic & Coordination ChemistryBased in part on the article Titanium: Inorganic & Coordination Chemistry by Charles A. McAuliffe & Neil Bricklebank which appeared in the Encyclopedia of Inorganic Chemistry, First Edition .

Abstract

This article describes the chemistry of titanium, with special focus on its inorganic coordination chemistry. This field has a rich history and has flourished in the years since the first industrial processes for isolation of titanium were introduced. Covered are the discovery of the metal, some of the physical properties of titanium and its complexes, and the unique coordination chemistry of titanium in its various oxidation states. The metal is commonly found in the +4 oxidation state, in which it behaves as a hard Lewis acid. Titanium complexes with formal oxidation states +3, and, much less commonly, +2, 0, and −1 are also known. The oxides, sulfides, halides, and complex halides are discussed. Complexes with carbon, nitrogen, oxygen, silicon, phosphorus, sulfur, and arsenic donor ligands are described. Structures and spectroscopic data are given for selected compounds. Interest in the coordination chemistry of titanium has been driven by important applications in materials chemistry and in catalysis.

Titanium-45 (45Ti) Radiochemistry and Applications in Molecular Imaging

“…Titanium is the ninth most abundant metal in the earth's crust and the second most abundant transition metal [1]. Titanium has been widely incorporated in many applications over the last few decades including personal hygiene products (including shampoo, deodorant, toothpaste, and sunscreens), medical implants, coating materials (in the paint industry), and food products (including dressings and beverages) [2,3].…”
