Abstract

Solution and frozen solution EPR spectra of $\alpha-1,2,3-[HPV(IV)V_2W_9O_{40}]^{6-}$ have been analyzed. The isotropic hyperfine coupling constants remain constant at 350-77 K, indicating that the unpaired electron is delocalized over three vanadium atoms probably even in the ground state.
