A 7 Coordinate Co-EDTA Complex - Crystal and Molecular-Structure of Aquo(Ethylenediaminetriacetatoacetic Acid)Cobalt(III) Dihydrate
We report the synthesis and characterization of a seven-coordinate cobalt(III) aquo-ethylenediaminetriacetatoacetic acid compound. The infrared spectrum of the complex is typical of cobalt- EDTA complexes. The structure of [Co(H2O)(C10H13N2O8]. 2H(2)O was determined by single-crystal X-ray diffraction. The complex displays a distorted pentagonal bipyramidal geometry similar to aquo-EDTA complexes of titanium, manganese and iron.
