Fig. 1: Elucidation of systematic synthesis and molecular architectures of isostructural Ag17, AuAg16, Ag13Cu4 and AuAg12Cu4 clusters shielded by o1-CBT ligands.

Systematic synthesis and molecular structures of isostructural Ag17, AuAg16, Ag13Cu4 and AuAg12Cu4 clusters, protected by twelve o1-CBT ligands (metallic gray: silver, yellow: gold, reddish orange: copper, cyan: sulphur, green: boron, dark grey: carbon and white: hydrogen). The tetrahedral framework, built on an icosahedron is shown at the center.
