Up to fourfold-bridged macrocyclic compounds bearing triphenylmethane units which form a large molecular cavity were prepared for the first time.The macrobicyclus 4 crystallizes from acetonitrile as 1:1 adduct and from phenylacetonitrile as 1:3 adduct with the respective solvent.The X-ray structures of these complexes are compared with the related 1:5 adduct of 13 with benzene.
