Abstract

Single crystals of Cs₃Ln₇Te₁₂ (Ln = Sm, Gd, Tb) have been grown accidentally through the reaction of Ln and Te with a CsCl or Cs₂Te₃ flux at elevated temperatures. The crystal structures have been determined from single crystal X-ray diffraction data. These compounds, which are isostructural with Rb₃Yb₇Se₁₂, crystallize in space group Pnnm of the orthorhombic system with two molecules in the following cells: Cs₃Sm₇Te₁₂, a = 13.750(6), b = 28.332(7), c = 4.473(3) Å, T = 293 K; Cs₃Gd₇Te₁₂, a = 13.6064(13), b = 28.209(3), c = 4.4324(4) Å, T = 153 K; Cs₃Tb₇Te₁₂, a = 13.5708(16), b = 28.116(3), c = 4.4147(5) Å, T = 153 K.
