Abstract
Variable temperature 13C n.m.r. studies on [(η-C5H5)2Fe2(CO)3(CNR)](II; R = But) and (III; R = Ph) show that (II), which contains a terminally bonded CNR ligand, exhibits fluxional properties while (III), which contains a bridging CNR ligand, does not; it is also shown that 13C resonances of isonitrile ligands are diagnostic of the presence of bridging or terminal CNR groups.Keywords
