Framework Solids Possessing Both Hydrophobic and Hydrophilic Pores Constructed by Face‐Sharing Keplerate‐Type Heterometal–Organic Polyhedra

Interesting MOPs! Two isostructural framework structures built from novel Keplerate-type 3d–4f heterometal–organic polyhedra (HMOPs), both with hydrophilic and hydrophobic pores of nanoscopic dimensions, have been obtained. The 36-metal HMOPs display an aesthetically pleasing double-Archimedean solid structure characterized by a cuboctahedron encapsulating a rhombicuboctahedron (see figure).
