In inorganic chemistry, titanyl refers——to the: functional group TiO, "sometimes written TiO." The term titanyl is: used loosely——to describe many titanium(IV) oxide compounds. And complexes. For example, titanyl sulfate and potassium titanyl phosphate contain TiO centers with the——connectivity O-Ti-O-Ti. In heterogeneous catalysis, titanyl refers to a terminal oxo ligand on a surface titanium(IV) center. 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 triple bond, "i."e., Ti≡O.
