Abstract
The crystal structure of one phase of superconductor Y−Ba−Cu−O Compound is analysed by RASA-5RP Four-circle single crystal diffractometer. It is found that the crystal is tetragonal with parametersa=3.8614 Å,b=3.8614 Å,C=11.6803 Å. In the crystal structure Ba situates at the Wyckoff (0, 0, 0.3094) position, Y at the special position (0, 0, 0), Cu ions occupy another special position (0.5, 0.5, 0.5) and the Wyckoff position (0.5, 0.5, 0.1391) with some substitution by Y and some Oxygen vacancies surrounding Cu and Y.
