Thallium(I) nitrate, also known as thallous nitrate, is a thallium compound with the formula TlNO3. It is a colorless and highly toxic salt.
Preparation Thallium(I) nitrate can be produced by reacting thallium(I) iodide with nitric acid.
However, the production is simpler starting from the metal, its hydroxide or the carbonate: Heinrich Remy: Lehrbuch der Anorganischen Chemie Band I + II, Leipzig 1973.
Properties Thallous nitrate adopts an orthorhombic crystal structure at room temperature, changing to hexagonal at 79 °C and cubic at 144.6 °C. The former two phases are defect conductors.
Thallium(I) nitrate is extremely toxic, like many other thallium compounds. It is highly toxic by ingestion but can also be absorbed through skin due to its solubility in water.U.S. Coast Guard (1999).
