摘要：

The crystal structure of YBa2Cu3O6.5 was refined from X-ray data of a twinned crystal with a domain ratio 5:1. The earlier proposed model of alternately filled and empty Cu-O chains is verified. On the basis of 1290 measured superstructure reflections averaged to 244 independent intensities a structure analysis was performed revealing systematic shifts of the strongly scattering atoms Y, Ba, and Cu compared to YBa2Cu3O6.93. © 1993 Academic Press, Inc.
