Copper clusters are nanoscale materials comprised of a metal core or frame enclosed by a mantle of stabilizing ligands; their exploration offers progress in diverse fields, such as medicine, electronics, and fundamental chemistry as catalysts, reducing agents, corrosion inhibitors, and petroleum sweeteners. When stabilized with dithiocarbamate (DTC) ligands (L), copper clusters show a propensity for reversible hydrogen uptake and a remarkable versatility in size and shape as demonstrated by the…
