Three samples of YBa2 (Cuo.9oCoo.to)307\_~ were prepared by different heat treatments and studied by both neutron-and highresolution X-ray diffraction. Standard samples, prepared using sintering temperatures up to 950°C in flowing oxygen, were superconducting with a midpoint near 30 K. About 0.75 fo
