These two orbitals are called the e g orbitals (the symbol actually refers to the symmetry of the orbitals, but we will use it as a convenient name for these two orbitals in an octahedral complex). The other three orbitals, the d xy , d xz , and d yz orbitals, have lobes that point between the ligands and are called the t 2 g orbitals (again ... Orbitals of same symmetry and similar energy levels can then be mixed to form a new set of molecular orbitals with bonding, nonbonding, and antibonding characteristics.

A molecular orbital diagram, or MO diagram, is a qualitative descriptive tool explaining chemical bonding in molecules in terms of molecular orbital theory in general and the linear combination of atomic orbitals (LCAO) method in particular. A fundamental principle of these theories is that as atoms bond to form molecules, a certain number of atomic orbitals combine to form the same number of ...

chemical bonding - chemical bonding - Molecular orbitals of H2 and He2: The procedure can be introduced by considering the H2 molecule.
