Ligand Field Theory for Cr-CO

Before exploring the bonding in the Cr-CO complex, review the molecular orbitals for carbon monoxide.

The Ligand Field Theory energy diagram for complexation of a single carbon monoxide ligand by chromium(0) is shown below. Clicking on an orbital in the energy diagram displays the 90% isosurface for that orbital in the virtual reality display. For the sake of simplicity, interactions involving the chromium 4s and 4p orbitals are omitted.

For each molecular orbital

  1. Identify the metal and ligand orbitals that mix to form the molecular orbital.
  2. Identify whether the molecular orbital is σ, σ*, π, π*, or n in character.
  3. Identify whether the molecular orbital has primarily metal or ligand character.
