  "term": "Sandwich compounds",
  "field": "Chemistry",
  "definition": "Organometallic compounds where a metal atom is 'sandwiched' between two planar organic ligands, typically aromatic rings. The metal forms coordinate bonds with the pi-electron systems of both ligands. Ferrocene, with an iron atom between two cyclopentadienyl rings, is a classic example of this structural motif.",
