Crystal Structure, Electric and Magnetic Behavior of Ce2Pd9Sb3.

Abstract

A new ternary compound in the Ce-Pd-Sb system has been observed and studied by single crystal diffraction, magnetic susceptibility and resistivity. This new compound, Ce2Pd9Sb3, was determined to crystallize in the Y2Co3Ga9 structure type: Cmcm, a = 13.769(2)A,b = 8.0412(8)A, c= 9.348(1)A,wR2 = 6.7%, 709F( sup 2) values, and 42 variables. An anti-site relationship exists between the p-block and transition elements relative to the parent structure type. The magnetic susceptibility exhibits Curie-Weiss behavior with an effective cerium moment of 2.51(3)micro B, comparable to the free ion value of 2.54 micro B and negligible exchange (theta = 2(2)K). No ordering of moments is observed above 4.2K. Resistivity measurements indicate simple metallic behavior with no apparent evidence for interaction between the local cerium moments and conduction electrons. jg p3
