    Description

    Scandium triiodide, also known as scandium iodide, is an inorganic compound with the formula ScI3 and is classified as a lanthanide iodide. It is a yellowish powder. It is used in metal halide lamps together with similar compounds, such as caesium iodide, because of their ability to maximize emission of UV and to prolong bulb life. The maximized UV emission can be tuned to a range that can initiate photopolymerizations.
    Scandium triiodide adopts a structure similar to that of iron trichloride (FeCl3), crystallizing into a rhombohedral lattice. Scandium has a coordination number of 6, while iodine has a coordination number of 3 and is trigonal pyramidal.
    The purest scandium triiodide is obtained through direct reaction of the elements:
    2 Sc + 3 I2 → 2 ScI3
    Alternatively, but less effectively, one can produce anhydrous scandium triiodide by dehydrating ScI3(H2O)6.
