Abstract

New interlanthanide selenides Ln₄Yb₁₁Se₂₂ (Ln = Ce, Sm, Gd) were synthesized from reactions of their constituent elements at 1123 K. These ordered compounds are isostructural with Ce₄Lu₁₁S₂₂, crystallizing with two formula units in the monoclinic space group C2/m. The structure consists of a network of six- and seven-coordinate Yb atoms penetrated by Ln₂Se₁₃ infinite chains. Gd₄Yb₁₁Se₂₂ has an antiferromagnetic transition at T_N = 2.29 K. Gd₄Yb₁₁Se₂₂ is a semiconductor with a resistivity of 103 Ω cm at 298 K.
