Copper Oxide - an overview | ScienceDirect Topics

Copper oxides are unusual in two respects. First, octahedral-site Cu(II): t 6 e 3 contains a single e hole in the 3d shell, which makes it orbitally degenerate and therefore a strong Jahn–Teller ion; consequently, Cu(II) ions normally occupy octahedral sites that are deformed to tetragonal (c/a > 1) symmetry by Jahn–Teller orbital ordering. However, in the absence of a cooperativity that ...
