Abstract
Rietveld analysis of powder neutron diffraction pattern recorded on Sr -based 1201-phase superconductor (T-c=53 K), (Hg0.7Cr0.3)Sr2CuO4+delta shows that the oxygen atoms at O(3) site are disordered at x=y=0.3712 . This fourfold split site has a total combined occupancy of similar t o 80% and is the only occupied site in the (Hg, Cr)O plane.
