  "id": "MLC-T-CHM-007255",
  "term": "Metallocenes",
  "field": "Chemistry",
  "definition": "Organometallic compounds characterized by a transition metal atom sandwiched between two parallel cyclopentadienyl ligands. The ligands are bound to the metal through pi-bonds involving all five carbon atoms of each ring. Ferrocene, with the formula Fe(C5H5)2, is the archetypal metallocene and exhibits an 18-electron configuration, contributing to its high stability.",
