Iridium and rhodium coordination chemistry has been used to self‐assemble metallocryptands: Treatment of two equivalents of [Cp*M(solv) 3 ][BF 4 ] 2 (Cp*=C 5 (CH 3 ) 5 ; M=Rh, Ir; solv=acetone) with three equivalents of the bidentate ligand 1,3‐bis(aminomethyl)‐2,5‐dimethoxy‐4,6‐dimethylbenzene (L) afforded the first irido‐ and rhodio‐cryptands [(Cp*M) 2 L 3 ][BF 4 ] 4 in high yields (70–85 %). The use of less congested ligands increased the accessibility of the cavity of the metallocryptands and enabled the encapsulation of tetrafluoroborate ions (see scheme).
