As with most oxonium salts, it is not stable when undissolved, or under neutral to basic conditions, tending to decompose in those conditions to [[Titanium_trifluoride|titanium fluoride]]s or [[oxyhalides]]s. Under highly acidic conditions, it decomposes to [[titanium dioxide|titania]], which is accelerated by fluoride scavengers. Under highly basic conditions, it is hydrolysed to titanium hydroxide. A related salt is the anhydrous [[fluoronium]] hexafluoridotitanate(2-) or (H<sub>2</sub>F)<sub>2</sub>[TiF<sub>6</sub>].

Hexafluorotitanic acid (systematically named oxonium hexafluoridotitanate(2-)) is an inorganic compound with the chemical formula (H3O)2[TiF6].

As with most oxonium salts, it is not stable when undissolved, or under neutral to basic conditions, tending to decompose in those conditions to titanium fluorides or oxyhalides. Under highly acidic conditions, it decomposes to titania, which is accelerated by fluoride scavengers. Under highly basic conditions, it is hydrolysed to titanium hydroxide. A related salt is the anhydrous fluoronium hexafluoridotitanate(2-) or (H2F)2[TiF6].
