摘要：

Preparation and resolution procedures are reported for a series of cobalt(III) complexes with the tetradentate ligand ethylenediamine-N,N′-diacetic acid (EDDA) and a carbonate, oxalate, or malonate anion. Proton magnetic resonance was used to establish the trans coordination of the oxygens of EDDA in isomers studied. Absolute configurations of the new complexes are assigned by comparison of their CD curves with that of (+)589-trans-Co(EDDA)en+, for which the absolute configuration is known. Rotational strengths of the d-d transitions were found to be determined largely by the EDDA and to be quite insensitive to the bidentate ligand used. © 1969, American Chemical Society.
