Circular Dichroism of Coordination Compounds. I. Splitting Patterns for Potassium Ethylenediaminetetraacetatocobaltate(III) and Model Compounds

Circular dichroism of a second geometrical isomer of ethylenediamine-N,N'diacetato-N,N'-di-3-propionatocobaltate(III) ion

“…e Reference 10. 7 The variation of emax between 73.0 and 76.0 presumably results from the deprotonation of Co(NH3)5C204H2+. The pK of this cation at 25°is close to 2.10,13…”

The Optical Resolution and Circular Dichroism of trans(N)-oxalatobis(amino-acidato)cobalt(III) Complexes

“…It has been recently recognized that CD (circular dichroism) spectra are extremely useful in assigning the split components of d-d transition bands of metal complexes. [1][2][3][4] The CD spectra1) of (+)546-Na[Co(ox)2(en)], for example, show two and three components in its first and second absorption bands respectively, while these splittings have never been detected in its ordinary absorption spectrum. Furthermore, considerable progress has been made in the field of the stereospecific separation of the optical isomers of metal complexes with optically active ligands.5) These investigations have also been made on the basis of their CD spectra mainly.…”

Circular Dichroism of Copper(II) Complexes with Optically Active Amino Acids

“…-97 «-Butyl +0.7 (4.4) + 16 -1.8 (1.7) -105 Isopropyl + 5. 3 1 With the exception of the methyl compound, the data are taken from ref. 2. Values in parentheses are maximum per cent optical purities calculated on the basis of the rotations listed in the adjoining column.…”
