Tin(IV) nitrate is the inorganic compound with the formula Sn(NO3)4. It is a white volatile solid, reflecting its molecular structure.
Structure
[edit]Like titanium(IV) nitrate, Sn(NO3)4 features four bidentate ligands. The eight Sn–O bonds are 2.161 Å in length. The molecule has idealized D4d symmetry.[3]
Production
[edit]It was first prepared in the 1960s. Tin(IV) chloride was added to dinitrogen pentoxide at −78 °C, which produced tin(IV) nitrate and nitryl chloride:[4]
- SnCl4 + 4 N2O5 → Sn(NO3)4 + 4 NO2Cl
Reactions
[edit]This compound is sensitive to water, it hydrolyzes into tin(IV) oxide and nitrogen dioxide. Tin(IV) nitrate reacts with trifloroacetic acid anhydride to yield (NO2+)2[Sn(OOCCF3)62−] which is a nitronium salt. With trifluoroacetic acid a similar compound solvated with trifluoroacetic acid is produced.[5]
It also reacts with acetic anhydride or acetic acid to produce tin(IV) acetate and with nitric oxide to produce tin(IV) oxynitrate.
The reaction of tin(IV) nitrate with triphenylphosphine and triphenylarsine yields dinitratotin(IV)bis(diphenylphosphonate) and dinitratotin(IV)bis(diphenylarsonate).[5]
