摘要：

The ternary stannide CePd0.427Sn2 was investigated by means of powder and single crystal X-ray diffraction, magnetic, electrical transport and heat capacity measurements. Phase stability studies showed that CePd0.427Sn2 forms within a linear composition range of the stannide CePd1-xSn2 set by 0.57 <= x <= 0.67. The compound was found to crystallize with a defect CeNiSi2-type structure, space group Cmcm, a = 4.558(3) angstrom, b = 17.410(11) angstrom, c = 4.4849(17) angstrom (single -crystal data). Physical measurements revealed that CePd0.427Sn2 is a Curie-Weiss paramagnet due to the sublattice of trivalent Ce ions. The compound exhibits weak Kondo effect and probably orders antiferromagnetically below about 1.5 K. (C) 2016 Elsevier B.V. All rights reserved.
