摘要：
The resolution of the enantiomers of tris (ethylenediamme)rathenium(III) iodide has been effected through fractional precipitation with optically active tris(oxalato)rhodate(III). Reduction of (—)350-Ru(en)33+ by zinc amalgam in an inert atmosphere yields (—)375-Ru(en)32+ with complete retention of optical activity. Absorption, optical rotatory dispersion, and circular dichroism data for both complexes are reported. The absolute configuration of (—)350-Ru(en)33+ was inferred by comparison with the tris(ethylenediamine)cobalt(III) enantiomers through the least soluble isomer method and the formation of active racemates; that of (—)375-Ru(en)32+ was inferred from the band assignments of the circular dichroism spectrum. Both (—)350-Ru(en)33+ and (—)375-Ru(en)32+ were found to have the d configuration. An external criterion for the completeness of resolution was obtained through the formation of active racemates. © 1969, American Chemical Society. All rights reserved.
