Different structure types of vanadyl(V) orthophosphate [i.e. (V V ≡O) 3+ orthophosphate] have been subjects of research due to their catalytic activity in the oxidation of n -butane to maleic anhydride. Electron paramagnetic resonance (EPR) spectroscopy can be exploited to elucidate the electronic s...
