Anhydrous titanium perchlorate decomposes explosively at 130 °C and melts at 85 °C with a slight decomposition.

[2] Titanyl perchlorate form solvates with water, dimethyl sulfoxide, dioxane, pyridine-N-oxide, and quinoline-N-oxide.

[2] Thermolysis of titanium perchlorate gives TiO2, ClO2 and dioxygen O2 The titanyl species TiO(ClO4)2 is an intermediate in this decomposition.

This forms a complex with Cl2O6 which when warmed to 55° in a vacuum, sublimes and can crystallise the pure anhydrous product from the vapour.

[1] In the salt dicaesium hexaperchloratotitanate, Cs2Ti(ClO4)6 the perchlorate groups are monodentate, connected by one oxygen to titanium.
