  "term": "Phosphoranes",
  "field": "Chemistry",
  "definition": "Neutral pentacoordinate phosphorus compounds containing a central phosphorus atom with five covalently bonded substituents, having the general formula PR₅. The parent compound is PH₅, also known as λ⁵-phosphane. These species adopt a trigonal bipyramidal geometry, which can undergo rapid intramolecular ligand exchange through a process called Berry pseudorotation.",
