Only one positional isomer is obtained from the assembly of 21 small components. A triangular molecular panel with five coordination sites is assembled upon complexation with [Pd II (en)] (en=ethylenediamine) into a unique M 15 L 6 hexahedral coordination capsule (see X‐ray structure). The capsule can encapsulate/exchange organic guests reversibly through the clefts at the nonbinding sites of the capsule.
