L'adduit ainsi formé se nomme cryptate. Le terme est généralement limité à des entités moléculaires bicycliques ou oligocycliques. [...] Si on peut considérer qu'ils définissent une cavité dans laquelle un invité peut se cacher, on inclut quelquefois les assemblages correspondants de coordinats monocycliques (couronnes) dans ce groupe. Les coordinats polycoordinés cycliques coplanaires, tels les porphyrines, ne sont généralement pas considérés comme des cryptands. 3, record 1, French, - cryptand
