Stereospecific ligands and their complexes: Synthesis and characterization of the s-cis-K[Ru(S,S-eddp)Cl2]·3H2O

Abstract

In the reaction of ruthenium(III) chloride and an edda-like ligand ethylenediamine-N,N'-di-S,S-2-propionic acid (S,S-eddp) in aqueous solution led to the formation of only one of the three possible geometrical isomers potassium-s-cis-dichlorido-(ethylenediamine-N,N'-di-S,S-2-propionato)-ruthenate(III)--trihydrate, s-cis-K[Ru(S,S-eddp)Cl 2 ]·3H 2 O. The assumed geometry of the complex was based on its electronic absorption and infrared spectra.

Stereospecific ligands and their complexes. VI. The crystal structure of (S,S)-ethylenediamine-N,N'-di-2-propanoic acid hydrochloride, (S,S)-H2eddp•HCl

“…6 According to these investigations, attention was mainly focused on the preparation, characterization and biological activity of metal complexes with stereospecific edda-type ligands (edda = ethylenediamine-N,N'-diacetato ion), such as the ethylenediamine-N,N'-di-(S,S)-2-propanoate ion and its derivatives.
