Diastereoisomeric forms of ligand-bridged dimetallic diruthenium(II) and ruthenium(II)–osmium(II) species containing bidentate polypyridyl ligands
摘要:
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) = bridging ligand), together with the chromatographic separation and characterization of the diastereoisomeric pairs of the dimers.
