A molecular orbital description of the bonding in organometallic complexes

A molecular orbital description of the bonding in organometallic complexes. 

As also shown in Table 2 the metal orbitals may be further resolved in 

Syuunetiy with respect to rotation about the z-axis Symmetry with respect to rotation about the z-axis and inversion at the metal nucleus  

Symmetry Metal orbitals Symmetry Metal orbitals 

Since only those ligand and metal orbitals which have die same symmetry properties can overlap to form bonds, we may by symmetry considerations determine the fairly small number of combinations of ligand and metal orbitals which may give bond formation. It should be noted that we are restricting ourselves to the highest occupied and lowest unoccupied orbitals.
