Abstract

The crystal structure of (+)546-cis(O)-triammine(sarcosinate-N-propionato)cobalt(III) (+)546-ethylenediaminetetraacetato)cobaltate(III) monohydrate was solved by single crystal X-ray diffraction techniques. The crystal is orthorhombic, space group P212121, with a=10.792, b=26.816, c=8.203 Å, and Z=4. The final R value was 0.054. The absolute configurations of two complex ions were determined by means of anomalous dispersion using Cu Kα radiation. The coordinated asymmetric nitrogen atom of sarcosinate-N-propionate ligand takes an R configuration, and the (+)546-(ethylenediaminetetraacetato)cobaltate(III) ion Δ one.
