2 domain-specific abstractions whose origin domain is Coordination Chemistry.

• Nephelauxetic effect — The reduction of interelectronic repulsion parameters when a transition-metal ion forms a complex, interpreted as expansion or delocalization of its d-electron cloud through covalent metal–ligand interaction.
• Tanabe–Sugano diagram — A normalized energy-level diagram showing how electronic states of a transition-metal ion vary with ligand-field strength relative to interelectronic repulsion.
