• The optical resolution of [Pt(NH<SUB>3</SUB>)<SUB>2</SUB>(<I>N</I><SUP>1</SUP>-Me-(<I>S</I>)-pn)]Cl<SUB>2</SUB> is effected by using silver di-μ-(+)-tartrato(4−)-bis(antimonate(III)) (Ag<SUB>2</SUB>[Sb<SUB>2</SUB>(+)-tart<SUB>2</SUB>]) as the resolving agent. X-Ray structure analysis of the less soluble diastereoisomeric salt, (+)<SUB>350</SUB>-[Pt(NH<SUB>3</SUB>)<SUB>2</SUB>(<I>N</I><SUP>1</SUP>-Me-(<I>S</I>)-pn)][Sb<SUB>2</SUB>(+)-tart<SUB>2</SUB>]·H<SUB>2</SUB>O, revealed that the asymmetric secondary nitrogen is of the <I>R</I> configuration. The crystal is orthorhombic, with a P2<SUB>1</SUB>2<SUB>1</SUB>2<SUB>1</SUB> space group, <I>a</I>=19.302(7) Å, <I>b</I>=14.791(4) Å, <I>c</I>=7.925(2) Å, and <I>Z</I>=4. The structure was determined from counter intensity data and refined to <I>R</I> 0.049 using the least-squares method for 1955 independent non-zero reflections. The Pt atom has a square-planar coordination with 4 N atoms and both the N–CH<SUB>3</SUB> and C–CH<SUB>3</SUB> groups are equatorial with respect to the chelate ring. The circular dichroism spectrum of <I>R</I>-[Pt(NH<SUB>3</SUB>)<SUB>2</SUB>(<I>N</I><SUP>1</SUP>-Me-(<I>S</I>)-pn)](ClO<SUB>4</SUB>)<SUB>2</SUB>, which was obtained from the less soluble di-μ-(+)-tartrato(4−)-bis(antimonate(III)) salt, is presented and discussed on the basis of the distribution of the possible conformers, the relative abundances of which were infered from <SUP>13</SUP>C NMR data.
