Synthesis and X-ray structural study of a novel ruthenium(III)–ethylenediaminetetraacetate complex. The first compound showing an unusual coordination site for a carboxylic (glycine) group
Abstract
Reaction of hydrated ruthenium trichloride in HCl and ethylenediaminetetraacetic acid (H4edta) gives the antitumour complex [Ru(H3edta)Cl2]·4H2O whose X-ray structure shows the first example of a stable Ru–OCOHR (glycine) bond; this type of linking has been confirmed by IR and X-ray photoelectron spectroscopy.
