Oxygen Atoms

The bonding for oxygen atoms in heteratomic molecules is viewed as essentially covalent [e.g., MeOH, Me2C=O, MeCH(O), and MeC(O)OOH] and similar to that for carbon, nitrogen, and chlorine atoms. In contrast, a Lewis acid-base formalism often is used for metal-oxygen compounds with ionic interactions by dianionic oxo groups (e.g., [Ba2+O2-], [Fe6+(O2)4]2- , [Mn7+(O2-)4]-, and [(Cu+)2O2-]).
