Titanyl

In inorganic chemistry, titanyl refers to the functional group TiIVO, sometimes written TiO2+.

The term titanyl is used loosely to describe many titanium(IV) oxide compounds and complexes.

In heterogeneous catalysis, titanyl refers to a terminal oxo ligand on a surface titanium(IV) center.

[2] 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.
