A First Transition Series Pseudotetrahedral Oxynitride Anion: Synthesis and Characterization of Ba₂VO₃N

Abstract

Ammonolysis of reactive oxide precursors affords the vanadium(V) phase Ba(2)VO(3)N that is shown by X-ray and neutron powder diffraction and Raman spectroscopy to contain pseudotetrahedral VO(3)N(4-) anions. This is the first example of such species for the first transition series metals.
