title: Molecular recognition of star-burst tetranuclear Ru(III) complexes on a chirally modified clay surface.
abstract: Star-burst tetranuclear Ru(iii) complexes, Delta-(or Lambda-)[{Delta-(or Lambda-)-Ru(iii)(acac)(2)(taet)}(3)Ru(iii)] (acac = acetylacetonato; taet = tetraacetylethanato), were prepared and resolved into eight enantiomers on a column packed with an ion-exchange adduct of a clay and Delta-[Ru(ii)(phen)(3)](2+) (phen = 1,10-phenanthroline), demonstrating that the dual chiralities of the central and peripheral regions were discriminated on the modified clay surface.
