Abstract
Five new complexes, C1-cis(O)[Co(gly)2(en)]Br·3H2O, C2-cis(O)-[Co(gly)2(en)]Br·H2O, trans(N)-K[Co(ox)(gly)2], C1-cis(N)- and C2-cis(N)-Na[Co(ox)(gly)2], have been synthesized. The geometrical isomers of both the [Co(gly)2(en)]+ and the [Co(ox)(gly)2]− complex have been separated by ion-exchange column chromatography. The geometrical structures have been determined on the basis of the visible absorption spectra and of the NMR spectra, and from a consideration of the reaction processes of derivation. The visible and near-ultraviolet absorption spectra of a complete series of the sixteen complexes of the [Co(ox)x(gly)y(en)z] type, have been measured and discussed.Keywords
