摘要：

Five new analogues of the beta-CeNiSb3 family have been synthesized and found to be LnNi(Sn,Sb)(3) and isostructural to the previously reported beta-CeNiSb3. LnNi(Sn,Sb)(3) (Ln = Pr, Nd, Sm, Gd, or Tb) crystallizes in the orthorhombic space group, Pbcm, with lattice parameters of a similar to 12.9 angstrom, b similar to 6.1 angstrom, c similar to 12.0 angstrom. The structure consists of layers of nearly square nets of X (X = Sn/Sb) atoms and highly distorted NiX6 octahedra. Lanthanide atoms are located between layers of X and NiX6 octahedra. All analogues are metallic and experimental effective magnetic moments are in agreement with the respective Ln(3+) calculated moments. (C) 2008 Elsevier Inc. All rights reserved.
