If no methyl groups are present to fill the gaps, up to six isopropyl substituents can be accomodated easily without significant steric strain: Five out of six structurally characterized 1,1′,2,2′,4,4′-hexaisopropylmetallocenes of 3d transition metals uniformly show a centrosymmetric conformation with the methine C-H bond of the isolated isopropyl groups in 4 and 4′ position oriented towards the metal and the respective methyl groups stretched out close to the ring plane, one example exhibits a more eclipsed conformation: D.J.
