Abstract
[Ir4(CO)11(CNBut)] has been prepared and shown (by X-ray crystallography and 13C n.m.r. studies) to be the first example of a derivative of Ir4(CO)12 without bridging carbonyl groups; variable temperature 13C n.m.r. spectra establish carbonyl scrambling via a triply bridged intermediate, i.e., the formal inverse of the C3v→Td scrambling mechanism proposed for [Rh4(CO)12].Keywords
