Subcomponent self-assembly of pseudo-cube6, from the reaction ofFwith 2-formylpyridine and zinc(II) triflimide in acetonitrile. Arelative arrangement of the six rectangular subunits (inset, left) was observed, contrasting with the configuration of the other pseudo-cubes discussed herein. The non-crystallographicC3axis is drawn to help visualize the idealizedD3symmetry of6. The different edge types within6are identified using different colors, and are labelled I, II and III, respectively, on the cut-out of a single face (inset, right). Disorder, anions, hydrogen atoms and solvent molecules are omitted from the crystal structure of6for clarity. C - gray, N - blue,fac- ZnII- purple,fac- ZnII- yellow.
