Abstract
Cu and C substitution for Hg in Hg-based cuprate superconductors is di scussed. The large Hg Debye-Waller factor usually obtained from refine ments. based on diffraction data should be interpreted as an indicatio n of carbon substitution for the Hg cations. This assumption is corrob orated by HREM, powder x-ray anomalous dispersion, and powder neutron diffraction investigations.
