✦ Synopsis

Ligand-stabilized, nanosized metal clusters have been proposed as an ultimate solution for nanolithography and microelectronics. [1] In this context metal carbonyl clusters could also play a role as they are potential nanocapacitors. However, for the cluster to truly function as a capacitor, its CO shell should effectively insulate the metal core, and it should be able to reversibly accept and donate electrons. At present there is no evidence of intermolecular exchange of electrons between differently charged carbonyl clusters, at least on the EPR timescale. They act as quantum dots, in which the cluster valence electrons are confined. [2] However, most metal carbonyl clusters displaying redox behavior have fortuitously been obtained. [3] COMMUNICATIONS
