Six new analogues of the β-CeNiSb3 family have been synthesized and characterized by single crystal X-ray diffraction. β-LnNiSb3 (Ln is Pr, Nd, Sm, Eu, Gd, and Tb) crystallizes in the LaPdSb3 structure type. The unit cell parameters of β-LnNiSb3 are approximately a ~ 12.9 Å, b ~ 6.1 Å, c ~ 11.9 Å. The structures consist of layers of nearly square nets of Sb atoms and highly distorted NiSb6 octahedra. Rare-earth atoms in square antiprismatic coordination are located between the layers of Sb and NiSb6 octahedra. The structures and properties of the rare earth analogues will be compared and discussed.
