Neodymium(III) sulfide is a inorganic chemical compound with the formula Nd₂S₃^[2] composed of a two neodymium atoms in the +3 oxidation state and three sulfur atoms in the -2 oxidation state. Like other rare earth sulfides, neodymium(III) sulfide is used as a high-performance inorganic pigment.^[3]

Preparation

Neodymium(III) sulfide can directly be produced by reacting neodymium with sulfur:^[4]^[5]

2Nd + 3S → Nd₂S₃

It can also be produced by sulfidizing neodymium oxide with H₂S at 1450 °C:^[4]^[6]

Nd₂O₃ + 3 H₂S → Nd₂S₃ + 3 H₂O

Properties

Neodymium(III) sulfide is (as γ-form) a light green solid. The compound comes in three forms.^[3] The α-form has an orthorhombic crystal structure, the β form has a tetragonal crystal structure, and the γ form has a cubic crystal structure. At 1650 °C in a vacuum, the γ compound decomposes to form neodymium monosulfide.^[6]

Neodymium(III) sulfide has a high melting point and a lot of polymorphic forms which make it difficult to grow.^[2] When heated, neodymium sulfide can lose sulfur atoms and can form a range of compositions between Nd₂S₃ and Nd₃S₄. Neodymium(III) sulfide is an electrical insulator.^[4]
