Scandium(III) sulfide is a chemical compound of scandium and sulfur with the chemical formula Sc 2 S 3. It is a yellow solid. Structure
Scandium monosulfide is a chemical compound of scandium and sulfur with the chemical formula ScS. Although its formula might suggest that it is a compound of scandium(II), i.e. [Sc 2+][S 2−], ScS is probably more realistically described as a pseudo-ionic compound, containing [Sc 3+][S 2−], with the remaining electron occupying the conduction band of the solid.
Scandium is a chemical element with the symbol Sc and atomic number 21. It is a silvery-white metallic d-block element . Historically, it has been classified as a rare-earth element , [ 9 ] together with yttrium and the lanthanides .
Scandium sulfide can refer to two different sulfides of scandium: Scandium monosulfide, ScS; Scandium(III) sulfide, Sc 2 S 3; Detailed information on each of these ...
In all four halides, the scandium is 6-coordinated. They can be prepared by reacting scandium oxide or scandium hydroxide with the corresponding acid: [3] Sc(OH) 3 + 3 HX → ScX 3 + 3 H 2 O. The halides are Lewis acids; for example, ScF 3 dissolves in a solution containing excess fluoride ion to form [ScF 6] 3−. The coordination number 6 is ...
