摘要：

The crystal structure of BaCuO2 has been redetermined by single crystal X-ray study on a crystal obtained as a parasitic phase during preparation of YBa2Cu3O7. The formula is Ba0.92Cu1.06O2.28 with a = 18.347(2) Å in the cubic space group Im3m. Reflections numbering 10,288 were collected and the structure was refined to Rw = 0.031 on the basis of 496 unique reflections. The structure is composed of an ordered and a disordered part of copper-oxygen units. The results for the ordered part confirm earlier structure determinations. The disorder is discussed in detail. © 1991.
