It is a white solid that forms by treatment of titanium dioxide with sulfuric acid, either directly or indirectly.

[1] A number of methods provide titanium(IV) sulfates.

One approach begins with K2TiO(C2O4)2·2H2O, which can be obtained from hydrous titanium(IV) oxides.

This salt is treated with hot aqueous sulfuric acid to degrade the oxalate:[2] 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.
