35 octahedral molecular orbital diagram
To describe the five bonding orbitals in a trigonal bipyramidal arrangement, we must use five of the valence shell atomic orbitals (the s orbital, the three p orbitals, and one of the d orbitals), which gives five sp 3 d hybrid orbitals. With an octahedral arrangement of six hybrid orbitals, we must use six valence shell atomic orbitals (the s ... The tetrahedral MO diagram is similar to the octahedral molecular orbital diagram. On the left, the metal ion orbitals are present, and on the right side are the ligand orbitals. The center depicts the orbitals of the metal complex. There are four ligands in tetrahedral complexes.
Molecular orbital diagram for a simple octahedral complex. This is qualitatively equivalent to the results of the simpler crystal field theory, which ignores orbital overlap with the ligand orbitals and uses just the electrostatic repulsion of the metal d-orbitals and the negative charges of the ligands.

In an octahedral complex, the molecular orbitals created by coordination can be seen as resulting from the donation of two electrons by each of six σ-donor ligands to the d-orbitals on the metal. In octahedral complexes, ligands approach along the x-, y- and z-axes, so their σ-symmetry orbitals ...
Simple Molecular Orbitals - Sigma and Pi Bonds in Molecules An atomic orbital is located on a single atom. When two (or more) atomic orbitals overlap to make a bond we can change our perspective to include all of the bonded atoms and their overlapping orbitals. Since more than one atom is involved, we refer to these orbitals as molecular orbitals.

Molecular orbital theory of transition metal complexes. The characteristics of transition metal-ligand bonds become clear by an analysis of the molecular orbitals of a 3d metal coordinated by six identical ligands in octahedral complexes [ML 6].As the result of the interaction between the metal d and ligand orbitals, bonding, non-bonding and anti-bonding complex molecular orbitals are formed.
A molecular orbital diagram which estimates the energies of the bonding (show above) antibonding and non-bonding orbitals is shown below. Since there is a large disparity in energy between the ligand orbitals and the metal orbitals, the lower lying molecular orbitals in the diagram are essentially ligand orbitals.
