Synthesis and crystal structure of 2H – CuAlO2

Abstract

2H – CuAlO₂ was obtained by reaction of Cu₂O and Al₂O₃ in a PbO flux. The crystal structure, which represents a 2H-stacking variant of the delafossite type of structure, was refined using single crystal X-ray diffractometer data (P6₃/mmc; a = 285,8(2), c = 1129,3(2) pm; Z = 2; R = 0,057; 122 independent observed reflexions).
