Tungsten pentoxide (W2O5) was reported in early literature but proved to have the stoichiometry W18O49.[1] Sometimes called mineral blue, it is a blue solid formed by the reaction of tungsten trioxide, WO3, and tungsten metal at 700 °C.[1]

Intermediate oxides of tungsten

There are a number of these unusual intermediate oxides formed from reacting metal and trioxide namely, W20O58, W24O70.[1] W18O49 contains both octahedral and pentagonal bipyramidal co-ordination of the metal atoms by oxygen.[1]
