Significance

The self-assembly of a giant sphere-shaped complex comprised of 24 Pd²+ ions and 48 bidentate ligands (1a-c) is reported. In addition to confirming the structure of this multicomponent system by X-ray crystallography, the authors also show the system has a critical dependence on the bond angle of the bridging ligand. Replacing the central thiophene unit with a furan (exchanging 2 for 1) results in the exclusive formation of Pd12 2 24 polyhedra.
