Na4 V2 C2 S2 O14

Na₄V₂C₂S₂O₁₄ is a mixed-valence vanadium-containing ceramic compound combining oxidic and sulfidic anionic frameworks, representing a synthetic phase in the sodium vanadium oxysulfide family. This material is primarily of research interest for energy storage and catalytic applications, where the structural diversity of vanadium oxidation states and the dual anionic system (oxide and sulfide) offer potential for electrochemical activity and redox-based functionality. Compared to conventional vanadium oxides or simple sulfides, the mixed-anion architecture may enable tuned ionic diffusion, electronic conductivity, or catalytic selectivity, making it a candidate for advanced battery materials or heterogeneous catalysis research rather than current mainstream engineering use.
