中文摘要	We report on the synthesis, crystallographic analysis, and physical properties of the new intermetallic compound CePd4Sn. It crystallizes in the orthorhombic Cmce space group with cell dimensions a = 9.003(4) angstrom, b = 23.613(3) angstrom, c = 8.265(3) angstrom, Z = 16, Pearson code oS96 and adopts a site exchange variant of the Dy2Ni7Sn3 type. Chemical bonding is characterized by strong Pd-Pd and Pd-Sn interactions. The structure can be presented as a packing of condensed cerium polyhedra. The 4f-electron part of the electrical resistivity is in evidence of incoherent Kondo scattering near and below room temperature that originates from the Ce3+ local moment. The magnetic susceptibility demonstrates stable moment behavior down to similar to 100 K. Magnetic ordering, presumably of an antiferromagnetic nature, occurs below T-N = 0.9 K.
