Abstract

The environment of vanadium in α-Bi₄V₂O₁₁ was investigated by ⁵¹V solid state NMR studies.The NMR parameters used for the best-fit simulations show the presence of at least three different sites of vanadium, two tetrahedral and one bipyramidal trigonal (or distorted octahedral). ⁵¹V magic angle spinning NMR spectra obtained at different stages in the reduction of Bi₄V₂O₁₁ confirm the progressive V(V)–V(IV) reduction. The original upfield shifted signal is attributed to V(V) interacting with paramagnetic V(IV) in Bi₄V₂O_10.66.
