摘要：
The compound NaBa2Cu3O6 was prepared heating of Na2O2, BaO2, Cu2O in closed Ag-tubes. X-single crystal investigations led to orthorhombic symmetry, space group D2h23-Fmmm; a = 8.4229; b = 11.4418 c = 14.4063 angstrom; Z = 8. Cu2+ and Cu3+ show square planar polygones of four and Na+ trigonal prisms of six O2-. The two barium point positons show coordination numbers C.N. = 8 and 6 + 4. The crystal structure is discussed.
