  "field": "Chemistry",
  "definition": "Divalent lead compounds of formula R2Pb, the lead analogues of carbenes, with lead in the +2 oxidation state and a sextet of valence electrons. Unlike carbenes they are comparatively stable, because lead favours the +2 state over +4 (the inert-pair effect), and species with bulky substituents can be isolated, for example lead(II) bis(trimethylsilyl)amide. Germylidenes and stannylidenes are the lighter analogues.",
