Abstract

The first Lewis-base adducts of a neutral p-block group metallocene, [(η-C5H5)2Pb·tmeda] 1 and [η-C5H5)2Pb·4,4′-Me2bipy] 2, result from the addition of tmeda and 4,4′-Me2bipy to [Pb(η-C5H5)2](1:1 equiv.); X-ray and solution studies reveal that the Lewis bases are only loosely associated to the PbII centres in these complexes.
