V10O286

V10O286 is a vanadium oxide formulation that appears in some databases or informal discussions as a vanadium-oxide cluster or oxide-rich phase. There is no widely recognized, peer‑reviewed compound with this exact neutral formula, and it is best understood as an empirical or provisional notation rather than a defined molecular species.

Chemical interpretation and charge considerations suggest that a neutral V10O286 molecule would require an average vanadium oxidation state of about +57, which is not chemically feasible for vanadium under known chemistry. Consequently, if V10O286 were to correspond to a real material, it would more plausibly exist as an anionic cluster or as part of a crystalline lattice with counterions or protons balancing charge, or as a fragment of a larger oxide framework. It could also reflect a transcriptional or typographical error for a smaller, known polyoxovanadate such as a V10O28-type unit.

In the context of vanadium oxide chemistry, related structures often feature VO6 octahedra connected by V–O–V bridges, with varying degrees of hydration and protonation. Polyoxovanadates and other high-oxidation-state vanadium oxide frameworks exhibit rich redox chemistry and catalytic activity, but no standard description confirms a neutral V10O286 species. Any literature claiming a material with this exact formula would require verification by techniques such as single-crystal X-ray diffraction, mass spectrometry, and elemental analysis to establish composition, charge state, and structure.

Status and research prospects: V10O286 remains an uncommon or ambiguous designation. If encountered, it should be treated as provisional pending corroborating structural and compositional data. See also vanadium oxides, polyoxometalates, and vanadium redox chemistry.
