[en] Five new analogues of the β-CeNiSb₃ family have been synthesized and found to be LnNi(Sn,Sb)₃ and isostructural to the previously reported β-CeNiSb₃. LnNi(Sn,Sb)₃ (Ln=Pr, Nd, Sm, Gd, or Tb) crystallizes in the orthorhombic space group, Pbcm, with lattice parameters of a∼12.9 A, b∼6.1 A, c∼12.0 A. 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 Ln³⁺ calculated moments. - Graphical abstract: Five new single crystalline analogues of the β-LnNiSb₃ family (Ln=Pr, Nd, Sm, Gd, or Tb) have been synthesized and determined to be LnNi(Sn,Sb)₃. The structures are compared to the previously reported β-CeNiSb₃. Magnetic and transport behavior are reported and discussed
