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.
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]
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]
The complex has D2d symmetry, with four bidentate nitrate ligands. The N-O distances are 1·29 Å and 1·185 Å (noncoordinated). [6]
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]
Titanium nitrate is hygroscopic, converting to ill-defined hydrates. [14] The anhydrous material is highly reactive, even toward hydrocarbons. [14] Titanium nitrate also reacts with n-dodecane, [15] p-dichlorobenzene, anisole, and biphenyl. [15] [16]
It decomposes thermally to titanium dioxide. [17]
