  "term": "Back donation",
  "field": "Chemistry",
  "definition": "The synergistic interaction in coordination compounds where electron density is transferred from a filled metal d-orbital into an empty antibonding pi-orbital of a ligand. This process strengthens the metal-ligand bond by relieving electron density from the metal center. Carbonyl ligands, such as carbon monoxide, are well-known for their ability to participate in back donation.",
