Hybridization of Nd (fπ) and Ce (fπ) orbitals with composite O (pπ)- O (pπ) bonding/ Cu(dπ*)-O(pπ) antibonding orbitals at the Fermi energy (EF) is shown to promote high-Tc superconductivity in Nd 2−x Ce x CuO 4. Dynamic Jahn-Teller coupling of these hybrid molecular orbitals to the lattice leads to Cooper pairing as it does in other high-Tc superconductors, such as La 2−x Sr x CuO 4, where O(pπ) character at E F is dominant.
