Through SP-Sephadex ion exchange chromatography [Ru(Hdpa)<SUB>3</SUB>]<SUP>2+</SUP> and [Ru(bpy)<SUB>2</SUB>(Hdpa)]<SUP>2+</SUP> (Hdpa=di-2-pyridylamine) were resolved by the use of an aqueous sodium <I>d</I>-tartrate solution as the eluting agent. <I>Λ</I>-[Ru(Hdpa)<SUB>3</SUB>]<SUP>2+</SUP> and <I>Δ</I>-[Ru(bpy)<SUB>2</SUB>(Hdpa)]<SUP>2+</SUP> were eluted in the early fractions. The precipitation of diastereomers with dibenzoyl-<I>d</I>-tartrate was also successful in the resolution of [Ru(Hdpa)<SUB>3</SUB>]<SUP>2+</SUP> and [Ru(bpy)(Hdpa)<SUB>2</SUB>]<SUP>2+</SUP>. The absolute configurations of the complexes were assigned by referring to the signs of CD spectra at around 3.2–3.8 μm<SUP>−1</SUP>.
