STRUCTURE DETERMINATION AND MAGNETIC-SUSCEPTIBILITY OF GD2 3CR2S4/

Besides the (GdS)1.27CrS2 misfit layered compound, gadolinium forms an other compound with chromium and sulfur with the formulation Gd2/3Cr2S 4. Single crystals were obtained from a mixture of GdCrS3 and Gd2S3 us ing I2 transport. This paper presents the single crystal refinement an d the magnetic properties of this compound. The structure can be descr ibed on the basis of double rutile-type chains of [CrS6] octahedra tha t are linked by bicapped trigonal prisms centered by Gd. This structur e is reminiscent of the arrangement found in the Lillianite mineral fa mily. (C) 1994 Academic Press, Inc.
