Thorium triiodide is a binary inorganic compound of thorium metal and iodine with the chemical formula ThI
3.[1][2][3]

Synthesis

Th metal is heated with ThI
4 in a vacuum at 800 °C.[4]

Th + 3ThI
4 → 4ThI
3

Physical properties

Thorium triiodide is a black, violet-tinged, usually poorly crystallized mass. Formed crystals exhibit strong dichroism from violet to olive green under the microscope and are birefringent.[5] Above 550 °C, thorium(III) iodide decomposes to thorium(IV) iodide and thorium(II) iodide. β-thorium(III) iodide has an orthorhombic crystal structure with the space group Cccm (space group no. 66).[6] The α-form has a pseudoorthorhombic crystal structure.

Chemical properties

ThI
3 reacts with water to form thorium tetraiodide and thorium metal.[4]
