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] StructureScandium monosulfide adopts the sodium chloride crystal structure type.[1] SynthesisScandium 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 References1. ^1 2 3 {{cite journal | title = The Preparation, Properties, and Crystal Structures of Some Scandium Sulfides in the Range Sc2S3-ScS | first = J.
