Abstract:
Entangled (M 3 L 2 ) n polyhedral complexes represent a unique class of supramolecular architectures that are stabilized by relatively weak metal–acetylene interactions in cooperation with conventional metal–pyridyl coordination. Counter‐anion exchange of these complexes with a nitrate (NO 3 − ) ion triggered formal metal insertion between the metal centers, and a heteroleptic ternary coordination mode with acetylenic, pyridyl, and nitrate donors was generated on the metal centers. As a result, the main frameworks of the polyhedral complexes M 18 L 12 and M 12 L 8 were formally extended into a new series of concave polyhedra having the compositions M 21 L 12 and M 13 L 8 , respectively. This transformation also resulted in the local disconnection of the highly entangled trifurcate topology of the framework, providing clues toward the skeletal editing of extended and complex three‐dimensional (3D) architectures.
