Short description: Compound of neodymium and sulfur

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. It 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.^[3]

Preparation

Neodymium(III) sulfide can directly be produced by reacting neodymium with sulfur:^[3]^[4]

2Nd + 3S → Nd₂S₃

It can also be produced by sulfidizing neodymium oxide with H₂S:^[3]^[5]

Nd₂O₃ + 3 H₂S → Nd₂S₃ + 3 H₂O
