Colloid‐ chemically synthesized gigantic gold and silver clusters and microparticles have been investigated by high‐resolution electron microscopy. In the case of the gold samples decahedral and icosahedral, multitwinned and triangular flattened particles were characterized. In the silver samples there were extremely small particles (<40 Å, see right‐hand side of picture) whose structure is interpreted in terms of a pentagonal packing of the atoms. The inset shows a structural model (left, top) and a computer‐simulated image (left, bottom).
