σ- and π-Bonded dinitrile complexes of MnI and ReI carbonyl halides
Abstract
The existence of both monomeric π-bonded dinitriles and dimeric σ-bonded dinitriles is postulated and its is suggested that the monomeric π-complexes are the kinetically favoured species, whereas the σ-bonded complexes are the thermodynamically favoured form.
