A new intermediate phase in the Lu-S system, Lu2 + xS3, between the sulfur-rich end of the monosulfide homogeneity range and Lu2S3 was found to be isostructural with Sc2S3. The structure of Lu2 + xS3 is based upon the NaCl-type with a 12 times larger orthorhombic unit cell due to ordering on the vacant lutetium sites, and with ordered vacancies that differentiate it from Sc2S3.
