Abstract:

The ternary compound Ce8Pd24Sb is very close in composition to the intermediate valent binary Cepd3. A single crystal study yielded a cubic cell with a8.4611A, Pm3m symmetry with wR20.0412 based on 1453 reflections 222 unique and 16 parameters. This new structure type is composed of distorted perovskite and Cu3Au subcells arranged with the perovskite-like units centered on the corners of the cube. Fitting the magnetic susceptibility data above 100K to a Curie-Weiss expression yielded a Weiss constant of -153K anti-ferromagnetic and an effective high temperature moment per cerium of 2.454microB indicating trivalent behavior of the cerium atoms. No ordering was observed above 3K. jg
