Five new analogues of the {beta}-CeNiSb{sub 3} family have been synthesized and found to be LnNi(Sn,Sb){sub 3} and isostructural to the previously reported {beta}-CeNiSb{sub 3}. LnNi(Sn,Sb){sub 3} (Ln=Pr, Nd, Sm, Gd, or Tb) crystallizes in the orthorhombic space group, Pbcm, with lattice parameters of a{approx}12.9 A, b{approx}6.1 A, c{approx}12.0 A. The structure consists of layers of nearly square nets of X (X=Sn/Sb) atoms and highly distorted NiX{sub 6} octahedra. Lanthanide atoms are located between layers of X and NiX{sub 6} octahedra. All analogues are metallic and experimental effective magnetic moments are in agreement with the respective Ln{sup 3+} calculated moments. - Graphical abstract: Five new single crystalline analogues of the {beta}-LnNiSb{sub 3} family (Ln=Pr, Nd, Sm, Gd, or Tb) have been synthesized and determined to be LnNi(Sn,Sb){sub 3}. The structures are compared to the previously reported {beta}-CeNiSb{sub 3}. Magnetic and transport behavior are reported and discussed.
