摘要：

Nickel-based, complex reducing agent (NiCRA) prepared by reacting Ni(OAc)(2), NaH and t-BuONa in THF were studied by transmission electron microscopy. Nickel is in the form of 1 nm-large clusters. In presence of bipyridyl ligands particles as small as 0.5 nm are detected. The formation and stability of nickel clusters is attributed to the strong reducing potential of the NaH-t-BuONa mixture complexing the nickel clusters. Bipyridyl ligands exert an additional stabilization so that clusters containing less than 10 atoms could be present.
