Summary

NEUTRON POWDER DIFFRACTION HAS BEEN USED TO DEFINE THE STRUCTURE OF THIS HIGH-TEMPERATURE SUPERCONDUCTOR TO DETERMINE THE PRECISE OXYGEN CO-ORDINATION AND THE EFFECTIVE VALENCE OF COPPER. THE RESULTS ARE IN EXCELLENT AGREEMENT WITH THE DUPONT X-RAY STRUCTURE, CONFIRMING THE POSSIBLE SUBSTITUTION OF ABOUT 9% OF THE CALCIUM-SITES WITH THALLIUM.
