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 a=8.461(1)A, Pm3m symmetry with wR2=0.0412 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 -15(3)K (anti-ferromagnetic) and an effective high temperature moment per cerium of 2.45(4)microB indicating trivalent behavior of the cerium atoms. No ordering was observed above 3K. jg
