Abstract
Metallic clusters can be produced by contacting a metal salt such as a metal nitrate with an organic reducing agent. Metals can be selected from a group consisting of metals exhibiting octahedral coordination, and nitrates of the selected metal or metals are contacted with, for example nitrosobenzene. Binary, tertiary, or other clusters can be produced.
