This Demonstration introduces crystal-field theory, which describes the geometry and energetics of coordination complexes. According to this model, ligands bonded to transition metal cause splitting of the -orbitals by electrostatic repulsion between the electrons in the -orbitals and the negatively charged ligands.

Snapshots
Details
Snapshot 1: the splitting caused by the tetragonal field is shown; three orbitals increase their energy, while two decrease it
Snapshot 2: the splitting caused by the octagonal field is shown; three orbitals decrease their energy, while two increase it
Snapshot 3: planar complex derived from the octagonal field; starting levels are represented in red, while the final situation is black
