The Electronic Structure of Crystalline Lead Oxides : II. Chemical Bonding in the Crystalline Lead Oxides
A quantum‐chemical definition is proposed of the full atomic valence taking into account both, covalent and ionic components of chemical bonds formed by an atom in molecules or crystals. Atomic charges, covalent bond orders, and full atomic valencies of lead and oxygen atoms in the crystalline lead oxides are calculated in the framework of the LUC‐CNDO approach.
