Titanyl sulfate is the inorganic compound with the formula TiOSO4. It is a white solid that forms by treatment of titanium dioxide with fuming sulfuric acid. It hydrolyzes to a gel of hydrated titanium dioxide.[1] The structure consists of dense polymeric network with tetrahedral sulfur and octahedral titanium centers. The six ligands attached to titanium are derived from four different sulfate moieties and a bridging oxide. A monohydrate is also known, being prepared similarly to the anhydrous material. In the hydrate, one Ti–OS bond is replaced by Ti–OH2.[2]
