Synthesis of the delafossite-type CuInO2

A new delafossite type oxide CuInO2 was synthesized by cation exchange reaction of CuCl with LiInO2, which was produced from Li2O and In(OH)(3), An almost single phase was obtained at 350 degrees C for 144 h, The structure of CuInO2 was refined by Rietveld analysis and the final S value became 1.1636, CuInO2 is rhombohedral, R-3m, a = 3.2922 Angstrom, c = 17.388 Angstrom, (C) 2000 Academic Press.
