Abstract

Rb2Cu3CeTe5 has been synthesized from the reaction of Cu and Ce in a molten alkali metal/polytelluride flux. The compound crystallizes in the monoclinic space group, C2/m (no. 12) with a=18.6884(1) Å, b=6.2384(2) Å, c= 12.5264(3) Å, β=112.795(1)°, V=1346.34(5) Å3, and Z= 4. Rb2Cu3CeTe5 is two-dimensional with 1/∞ [Cu3CeTe5]2- layers built from one-dimensional 1/∞ [Cu2CeTe5]3- chains that are 'stitched' together by distorted tetrahedral Cu atoms; the compound is paramagnetic and a narrow-gap p-type semiconductor.
