Abstract
Metal-oxygen complexes containing Cu, Tl, Hg, Bi, and Pb cations are electronically active in superconducting copper oxides by stabilizing single phases with enhancedT c, whereas other metal-oxygen complexes deteriorate copper oxide superconductivity. Cu. Tl, Hg, Bi, and Pb in their actual oxidation states are closed-shelld 10 or inerts 2 pair ions. Their electronic configurations have a strong tendency to polarize the oxygen environment. The closed shelld ions with low-lyingnd 10↔nd 9(n+1)s excitations form linear complexes through\(d_{z^2 - s} \) hybridization polarizing the apical oxygens. Comparatively lownd 9(n+1)s excitation energies distinguish Cu1+,3+, Tl3+, Hg2+, from other closed-shelld 10 ions deteriorating copper oxide superconductivity, e.g., Zn2+.

The unified picture of superconductivity in oxides suggested in [3] labels the rare as “insulating.” Here we follow for convenience the four-number naming scheme labeling the metal-oxygen complexes in theP layer of [3] as “insulating,” and the “insulating” layers of [3] as “separating.”
