Abstract
The three clusters [Fe6Ni6N2 (CO)24]n- (n = 2-4) have been isolated, and their solid-state structures determined. The clusters are composed by three face-sharing octahedra, with the external ones filled by two interstitial nitride. The addition of electrons brings about swelling of the central, empty octahedron. Cyclic voltammetry shows that redox conversions of the three clusters are totally reversible. Extended Hückel and density functional calculations have been performed, to explain this behavior. © 2005 Académie des sciences. Published by Elsevier SAS.
