USES :

Scandium(III) chlorideis the inorganic compound with the formula ScCl3. It is a white, high-melting ionic compound, which is deliquescent and highly water soluble. Scandium(III) chloride is mainly of interest in the research laboratory. Both the anhydrous form and hexahydrate (ScCl3•6H2O) are commercially available.

ScCl3crystallises in the layered BiI3motif, which features octahedral scandium centres. Monomeric ScCl3is the predominant species in the vapour phase at 900 K, the dimer Sc2Cl6accounts for approximately 8%.The electron diffraction spectrum indicates that the monomer is planar and the dimer is bridged with four Sc-Cl bonds.
