Da. Reitsma et Fr. Keene, DIASTEREOISOMERIC FORMS OF LIGAND-BRIDGED DIMETALLIC DIRUTHENIUM(II) AND RUTHENIUM(II)-OSMIUM(II) SPECIES CONTAINING BIDENTATE POLYPYRIDYL LIGANDS, Journal of the Chemical Society. Dalton transactions, (18), 1993, pp. 2859-2860
A new general synthetic route is reported for dinuclear species of the
type [(L(t))2RuL(b)Ru(L)'2]4+ or [(L(t))2RuL(b)Os(L(t)')2]4+ (L(t), L
(t)' = bidentate polypyridyl ligands, L(t), not-equal L(t)'; L(b) = br
idging ligand), together with the chromatographic separation and chara
cterization of the diastereoisomeric pairs of the dimers.
