Tetramercaptotetrathiacalix[4]arene (LH<sub>4</sub> ) can be used as a coordination platform to bind four Cu<sup>I</sup> ions at the thiolate and thioether S atoms. Donor ligands such as phosphanes can stabilize the resulting [LCu<sub>4</sub> ] units, which then remain monomeric ([(Ph<sub>3</sub> PCu)<sub>4</sub> L]). In the absence of donor ligands, they aggregate, providing a hexamer ([LCu<sub>4</sub> ]<sub>6</sub> ) in high yields, with a hollow-sphere structure formed by an unprecedented Cu< ...[more]
