Abstract
A number of substituted butatriene‐bis‐tricarbonyliron complexes have been studied by ^13^C and ^1^H n.m.r. spectroscopy. Long range coupling values, J(CCCH), have confirmed chemical shift results that methyl and phenyl groups assume opposite orientations at the coordinated double bonds with the methyl group preferentially trans to carbon and the phenyl group preferentially trans to iron.
