Single crystals of the compounds Lu 2 Cu 2 O 5 (A) and Sc 2 Cu 2 O 5 (B) were prepared by melting the oxide mixtures (2 CuO : 1 Lu 2 O 3 , 2 CuO : 1 Sc 2 O 3 ) in a KF-flux. The crystal structures were investigated by single crystal X-ray data (Space group : C 2V 9 –P2 1 nb, 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 Ho 2 Cu 2 O 5 and differ from the Cu 2 In 2 O 5 type in respect of the Cu 2+ -coordination.
