Abstract

The compounds CsGd₂Cu₃Se₅ and CsTb₂Cu₃Se₅ have been obtained through the reaction of CsCl, Gd₂Se₃ or Tb₂Se₃, and Cu₂Se at 1123 K. These compounds crystallize in the RbSm₂Ag₃Se₅ structure type with four formula units in the space group Cmcm of the orthorhombic system in cells of dimensions at 153 K of a = 4.1417(3) Å, b = 14.6422(9) Å, c = 17.4543(11) Å, V = 1058.49(12) Å³ for CsGd₂Cu₃Se₅ and a = 4.1268(4) Å, b = 14.6204(14) Å, c = 17.3390(16) Å, V = 1046.16(17) Å³ for CsTb₂Cu₃Se₅. This structure consists of ten-membered pentagonal rings in which the alkali-metal atoms are situated. The three-dimensional anionic framework is built from LnSe₆ octahedra and CuSe₄ tetrahedra.
