Ytterbium(II) sulfide is a binary inorganic compound of ytterbium and sulfur with the chemical formula YbS.^[1]^[2]

Synthesis

Synthesis of ytterbium(II) sulfide can be via a reaction of pure substances in an inert atmosphere:^[3]

Yb + S → YbS

An alternative synthesis is by comproportionation of ytterbium(III) sulfide and ytterbium metal in vacuum at 1000–1100 °C:

Yb₂S₃ + Yb → 3YbS

Ytterbium(II) sulfide forms black crystals of cubic symmetry, space group Fm3m, cell parameter a = 0.5658 nm, Z = 4.^[4]

Ytterbium(II) sulfide demonstrates semiconductor behavior.^[5]
