摘要
Besides the (GdS)1.27CrS2 misfit layered compound, gadolinium forms another compound with chromium and sulfur with the formulation Gd2/3Cr2S4. Single crystals were obtained from a mixture of GdCrS3 and Gd2S3 using I2 transport. This paper presents the single crystal refinement and the magnetic properties of this compound. The structure can be described on the basis of double rutile-type chains of [CrS6] octahedra that are linked by bicapped trigonal prisms centered by Gd. This structure is reminiscent of the arrangement found in the Lillianite mineral family. (C) 1994 Academic Press, Inc.
