The term titanyl is used loosely to describe many titanium(IV) oxide compounds and complexes. For example, titanyl sulfate and potassium titanyl phosphate contain Ti<sup>IV</sup>O centers with the connectivity O-Ti-O-Ti. In heterogeneous catalysis, titanyl refers to a terminal oxo ligand on a surface titanium(IV) center.<ref>{{cite journal|title=The Role of Synchrotron-Based Studies in the Elucidation and Design of Active Sites in Titanium−Silica Epoxidation Catalysts|author=John Meurig Thomas |author2=Gopinathan Sankar |journal=Accounts of Chemical Research|year=2001|volume=34|pages=571–581|doi=10.1021/ar010003w}}</ref> 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.
