A metal complex is made up of a central metal atom and its ligands

•  Ligands can be classified according to their field strength or ligand strength.

•  Strong-field ligands repel the metal's electrons very effectively, producing large splits.

This means that the field is low spin and the lower energy orbitals to be filled first before the higher energy orbitals.

•  Weak-field ligands only partly repel the electrons, producing smaller splits.

This means that the field is high spin and the higher energy orbitals will be filled even if the lower energy orbitals are unfilled.
