Chiral Octahedra and Cuboctahedra

Self-assembly of the cuboctahedron 5.58 from 1 1 ratio of Zn(II)-cyclen and the tridentate ligand TCA (reproduced with permission from reference ). 

The ability of this chiral cage 5.58 to encapsulte chiral guest molecules such as (15,2/ ,4/ )-(—)-camphorsultam was investigated by NMR spectroscopy, indicating that an encapsulated chiral guest can control the exterior chirality of the assembly 5.58. 

Cuboctahedron 5.58 space filling viewed along C3-symmetry axis. The four units of tris(Ld -cycltn) are shown in light green, green, yellow and blue (reprinted with permission from reference ).
