Abstract
Single crystals of the compounds Lu2Cu2O5 (A) and Sc2Cu2O5 (B) were prepared by melting the oxide mixtures (2 CuO : 1 Lu2O3, 2 CuO : 1 Sc2O3) in a KF-flux. The crystal structures were investigated by single crystal X-ray data (Space group : C2V 9–P21nb, lattice constants (A): α = 1235.0, b = 1069.8, c = 340.5pm, (B): α = 1204.1, b = 1045.2, c = 322.0 pm). (A) and (B) are isotypic with Ho2Cu2O5 and differ from the Cu2In2O5 type in respect of the Cu2+-coordination.Keywords
