Titanium nitrate is the inorganic compound with formula Ti(NO3)4. It is a colorless, diamagnetic solid that sublimes readily. It is an unusual example of a volatile binary transition metal nitrate. Ill defined species called titanium nitrate are produced upon dissolution of titanium or its oxides in nitric acid.

Preparation

Similarly to its original method,[7][8] Ti(NO3)4 is prepared by the nitration of titanium tetrachloride using dinitrogen pentoxide[9] or chlorine nitrate:[10]

TiCl4 + 4 N2O5 → Ti(NO3)4 + 4
ClNO2

Hydrated titanium nitrate, the nitrate salt of the

aquo complex [Ti(H2O)6]3+, is produced upon dissolution of titanium compounds in nitric acid.[11]

Structure

The complex has D2d symmetry, with four bidentate nitrate ligands. The N-O distances are 1·29 Å and 1·185 Å (noncoordinated).[6]

Physical properties

In the infrared spectrum, it absorbs strongly at 1635 cm−1, assigned to a N-O vibrational mode.[12]

It is soluble in nonpolar solvents silicon tetrachloride and carbon tetrachloride.[13][8]

Reactions

Titanium nitrate is hygroscopic, converting to ill-defined hydrates.

p-dichlorobenzene, anisole, biphenyl,[15][16]

It decomposes thermally to titanium dioxide.[17]
