Abstract

The synthesis of several hydrocarbon biradicals consisting of two tetraphenylcyclopentadienyl moieties with different bridge fragments is described. The ESR powder spectra show that there is an intramolecular coupling of two unpaired electron spins to a triplet spin state. The magnitude of the zero field splitting (zfs) is used to discriminate between different molecular conformations. More detailed structural informations are ...
