A first transition series pseudotetrahedral oxynitride anion: Synthesis and characterization of Ba2VO3N
Ammonolysis of reactive oxide precursors affords the vanadium(V) phase Ba2VO3N that is shown by X-ray and neutron powder diffraction and Raman spectroscopy to contain pseudotetrahedral VO3N4- anions. This is the first example of such species for the first transition series metals.
