inorganic chemistry Inorganic chemistry deals with synthesis and behavior of inorganic and organometallic compounds. This field covers chemical compounds that are not carbon-based, which are the subjects of organic chemistry. The distinction between the two disc ...

, titanyl refers to the

functional group In organic chemistry, a functional group is a substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions. The same functional group will undergo the same or similar chemical reactions regardless of the res ...

Ti^IVO, sometimes written TiO²⁺. The term titanyl is used loosely to describe many titanium(IV) oxide compounds and complexes. For example, titanyl sulfate and

potassium titanyl phosphate Potassium is the chemical element with the symbol K (from Neo-Latin '' kalium'') and atomic number19. Potassium is a silvery-white metal that is soft enough to be cut with a knife with little force. Potassium metal reacts rapidly with atmosphe ...

contain Ti^IVO centers with the connectivity O-Ti-O-Ti. In

heterogeneous catalysis In chemistry, heterogeneous catalysis is catalysis where the phase of catalysts differs from that of the reactants or products. The process contrasts with homogeneous catalysis where the reactants, products and catalyst exist in the same phase. ...

, titanyl refers to a terminal oxo ligand on a surface titanium(IV) center.{{cite journal, title=The Role of Synchrotron-Based Studies in the Elucidation and Design of Active Sites in Titanium−Silica Epoxidation Catalysts, authors=John Meurig Thomas, Gopinathan Sankar, journal=Accounts of Chemical Research, year=2001, volume=34, pages=571-581, doi=10.1021/ar010003w There are a few molecular titanyl complexes where the oxo ligand is terminal, not bridging. In these cases the titanyl group is described as having a triple bond, i.e., Ti≡O.
