Abstract
The classic zigzagged chain structure of orthorhombic plumbocene, [Pb(η-C 5 H 5 ) 2 ] ∞ , is obtained by crystal growth from the vapour phase; however, crystallisation from toluene results in modification of the conformation of the polymer chain, as observed in the solvate [Pb(η-C 5 H 5 )·C 6 H 5 Me ] ∞ 1, and cyclisation into hexamers, as seen in the new hexagonal phase [Pb(η-C 5 H 5 ) 2 ] 6 2.Keywords
