We investigate the three-band extended Hubbard model for the CuO 2 planes of high-temperature superconductors. We consider the limit of U = I on Cu atoms and we include the nearest-neighbor Coulomb repulsion between holes on 2p x,y orbitals of oxygen and holes on 3d x 2 ร€y 2 or 3d 3z 2 ร€r 2 orbitals
