This formulation for this material assumes based on the observed geometry and the PO bond lengths that all of the terminal OH groups on the PO4groups including the unique central PO4 are protonated. Bond strengthbond length calculations based on the observed MoO bond lengths and the geometry about the Mo atoms clearly show the Mo to be in the + 5 oxidation state. If one assumes that all Mo atoms are Mo5⊕and the solvate water molecules are not protonated then the central phosphate is required to be H3PO4 consistent with the observed hydroge‐bonding pattern.
