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. , ScS is probably more realistically described as a pseudo-ionic compound, containing , with the remaining electron occupying the conduction band of the solid.

Structure

Scandium monosulfide adopts the sodium chloride crystal structure type.

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.

Sc + S → ScS
