%X From a comparison of &#946;-effects given by methyl substituents in tricarbonyldieneiron complexes with those of the corresponding uncomplexed 1,3-dienes, it is concluded that bonding to iron results in a change in p-bond orders of the ligand. This change is consistent with the structure (1) making an important contribution to bonding in these complexes.
