Two mixed ligand vanadium(III) complexes bis(acetylacetonato)(phenanthroline)vanadium(III) fluoroborate (1) and bis(acetylacetonato)(phenanthroline)vanadium(III) perchorate (2) have been prepared and characterized by UV–Vis, IR, 1H NMR spectroscopic techniques and single crystal X-ray diffraction. The electronic spectra are as expected for V(III) in an octahedral environment. The 1H NMR spectra are typical of paramagnetic V(III) species. The complexes have crystallized with dichloromethane solvate and are isomorphous. The coordination sphere is composed of vanadium in a distorted octahedral environment, ligated to two bidentate chelating acetylacetonate ligands through the oxygen atoms and two phenanthroline nitrogens.
Air-stable, non-oxo, mononuclear, 1,10-phenanthroline complexes of vanadium(III) containing acetylacetonate as co-ligands have been prepared and structurally characterized.Figure optionsDownload as PowerPoint slide
