Abstract

The compound CsScUSe₃(Se₂) has been synthesized by the reaction of U, Sc, and Se in a CsCl flux at 1173 K. Its structure is composed of infinite [^ScUSe5^-]∞2 sheets that are separated by Cs⁺ ions. The structure contains one Se₂^2- unit per U. Accordingly, the formula is charge balanced with U⁴⁺ and Sc³⁺ as Cs¹⁺Sc³⁺U⁴⁺(Se^2-)₃(Se₂^2-). From magnetic susceptibility measurements the magnetic behavior of CsScUSe₃(Se₂) can be divided into three different regions: paramagnetic, T>T_N; antiferromagnetic ordering, T<T_N; and ferromagnetic, T<T_c, where T_N and T_c are approximately 70 K and 25 K, respectively.
