Three Cr(CO) 3 units outside and two Cu 1 ions inside the cavity are contained in the dicationic cryptate 1 , prepared from [Cu(CH 3 CN) 4 ]ClO 4 and the appropriate macrobicycle. The cryptand is accessible in a one‐pot reaction in 74% yield from tere‐phthalaldehydetricarbonylchromium and tris‐(2‐aminoethyl)amine.
