Porous Metal−Organic Frameworks Based on Metal−Organic Polyhedra with Nanosized Cavities as Supramolecular Building Blocks:  Two-Fold Interpenetrating Primitive Cubic Networks of [Cu6L8]12+ Nanocages

Abstract

Discrete metal-organic polyhedra (MOP) with nanosized cavities and/or clusters of MOP could be prepared when C-3-symmetric facial ligands and a potential hexatopic Cu(II) ion are combined in the presence of perchlorate as a weak linker, while similar reaction conditions in the presence of a nitrate linker led to extended metal-organic frameworks made of MOP as supramolecular building blocks.
