Copper Oxide - an overview | ScienceDirect Topics

The copper-oxide superconductors all contain CuO 2 sheets in which any apical Cu-O bonds perpendicular to a sheet are significantly longer than the in-plane Cu-O bonds. This structural feature signals full occupancy of the (3z 2 –r 2) orbitals of an e-orbital pair.The parent compounds of the superconductive systems contain all Cu II in the CuO 2 sheets, which leaves the in-plane (x 2 – y 2 ...
