The high-symmetry “buckyball” structure of C60 captured the imagination as a reflection of nature's intrinsic elegance at the molecular scale. Wang et al. now report a similar icosahedral cage composed of 180 silver ions, capped and compensated by an array of organic thiolate and sulfonate ions. Fragile crystals emerged after heating simple precursors in methanol and were characterized by x-ray diffraction, mass spectrometry, and nuclear magnetic resonance spectroscopy. The ∼2.5-nanometer-diameter cage manifested weak luminescence in the near infrared.
