Organometallics ; 17 (1998), 11. - S. 2155-2161 eng Chiral metallocene complexes with a dialkylphosphonium bridge and different main-group metal (Li, K, Ba) centers have been synthesized from phosphonium-bridged bis(cyclopentadienyl) ligands in their mono- and diprotonated forms. NMR studies in solution and crystal structures of the kalocene Me<sub>2</sub>P(2-Me-4-<sup>t</sup>Bu-C<sub>5</sub>H<sub>2</sub>)<sub>2</sub>K and of the barocene Me<sub>2</sub>P(2-Me-4-<sup>t</sup>Bu-C<sub>5</sub>H<sub>2</sub>)<sub>2</sub>Ba(THF)<sub>3</sub><sup>+</sup>BPh<sub>4</sub><sup>-</sup> show that these metallocenes are obtained in form of their racemic diastereomers.
