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.[1]
Structure
Scandium monosulfide adopts the sodium chloride crystal structure type.[1]
Synthesis
Scandium monosulfide can be prepared by heating a mixture of scandium metal and powdered sulfur in the absence of air to 1150 °C for 70 hours.[1]
- Sc + S → ScS
