  2. Vanadium phosphates - Wikipedia

    en.wikipedia.org/wiki/Vanadium_phosphates

    Vanadium(III) phosphates lacking the oxo ligand have the formula VPO 4 •H 2 O and VPO 4 •2H 2 O. The monohydrate is isostructural with MgSO 4 •H 2 O [8] It adopts the structure of the corresponding hydrated aluminium phosphate. Oxidation of VPO 4 •H 2 O yields the two-electron electroactive [9] material ε-VOPO 4 [10]

  3. Vanadium compounds - Wikipedia

    en.wikipedia.org/wiki/Vanadium_compounds

    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.

  4. Phosphide - Wikipedia

    en.wikipedia.org/wiki/Phosphide

    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.

  5. Group 5 element - Wikipedia

    en.wikipedia.org/wiki/Group_5_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 ...

  8. Oxyphosphides - Wikipedia

    en.wikipedia.org/wiki/Oxyphosphides

    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.

  9. Phosphoric acids and phosphates - Wikipedia

    en.wikipedia.org/wiki/Phosphoric_acids_and...

    The general formula of a phosphoric acid is H n+2−2x P n O 3n+1−x, where n is the number of phosphorus atoms and x is the number of fundamental cycles in the molecule's structure, between 0 and ⁠ n + 2 / 2 ⁠. Pyrophosphate anion. Trimethyl orthophosphate.
