Heating a suspension of vanadium pentoxide and phosphoric acid gives VOPO 4 •2H 2 O, isolated as a bright yellow solid. [4] According to X-ray crystallography, the V(V) centers are octahedral, with long, weak bonds to aquo ligands. [5] Reduction of this compound with alcohols gives the vanadium(IV) phosphates.
In chemistry, a phosphide is a compound containing the P 3− ion or its equivalent. Many different phosphides are known, with widely differing structures. [ 1 ] Most commonly encountered on the binary phosphides, i.e. those materials consisting only of phosphorus and a less electronegative element.
Vanadium forms oxides in the +2, +3, +4 and +5 oxidation states, forming vanadium(II) oxide (VO), vanadium(III) oxide (V 2 O 3), vanadium(IV) oxide (VO 2) and vanadium(V) oxide (V 2 O 5). Vanadium(V) oxide or vanadium pentoxide is the most common, being precursor to most alloys and compounds of vanadium, and is also a widely used industrial ...
Vanadium compounds are compounds formed by the element vanadium (V). The chemistry of vanadium is noteworthy for the accessibility of the four adjacent oxidation states 2–5, whereas the chemistry of the other group 5 elements , niobium and tantalum , are somewhat more limited to the +5 oxidation state.

Oxyphosphides are chemical compounds formally containing the group PO, with one phosphorus and one oxygen atom. The phosphorus and oxygen are not bound together as in phosphates or phosphine oxides, instead they are bound separately to the cations (metals), and could be considered as a mixed phosphide-oxide compound.
