摘要

A new barium ytterbium indium selenide, Ba_2YbInSe_5, was obtained by conventional high temperature solid state reaction. The compound crystallizes in the noncentrosymmetric space group Cmc2_1 of the orthorhombic system. The structure contains infinite one-dimensional anionic chains ~1 _∞[YbInSe_5]~(4-), which are built from YbSe_6 octahedra and InSe_4 tetrahedra and separated by Ba~(2+) cation. The magnetic measurement indicates that the compound is paramagnetic. In addition, the calculated bandgap is 0.29 eV.
