dc.description.abstractA series of chiral ansa-magnesocene complexes with dimethylsilanediyl- or ethanediyl-bridged, substituted cyclopentadienyl or indenyl ligands, prepared in form of their THF adducts, has been structurally characterized by diffractometric crystal structure determination and by NMR studies in solution. The hapticities of the ring ligands vary between η1 and η5, depending on the nature of the interanular bridge and the C5 ring substituents. A racemic configuration is preferred by Mg bis-indenyl complexes with either Me2Si- or C2H4-bridges in the solid state and in solution, while meso isomers predominate for t-butyl-substituted ansa-magnesocenes.eng
