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. [Sc2+][S2−], ScS is probably more realistically described as a pseudo-ionic compound, containing [Sc3+][S2−], with the remaining electron occupying the conduction band of the solid.
