Abstract

The available experimental data for 105 distinct families of high-T-c oxocuprate superconductors point to the presence of a 'magic' intrasheet Cu-O separation of 1.923 angstrom. which yields the highest T-c values at ambient pressure (Rao 1995). The interpretation with Burdett's model (1993), along with electronic band structure calculations is centered at a crossing of the O- and Cu-predominated sigma bands and points to the significance of the electron-phonon coupling for these materials.
