Neodymium(III) sulfide is a inorganicchemical 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]
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]
