  "term": "Nido-",
  "field": "Chemistry",
  "definition": "A prefix used in inorganic nomenclature to describe a cluster compound that has a cage structure derived from a closed (closo-) structure by removing one vertex. This results in a cluster that is nearly closed but has one open face. Nido-clusters typically have n+2 skeletal electron pairs, where n is the number of vertices in the cluster framework.",
