Na6 Mn2 P2 C2 O14

Na6Mn2P2C2O14 is a mixed-valence sodium manganese phosphate-carbonate compound that functions as a semiconductor material. This polyanion-framework compound belongs to the family of inorganic hybrid materials being explored for energy storage and electrochemical applications, where the framework structure and mixed oxidation states of manganese can facilitate ion transport and electronic conductivity. While primarily in the research phase rather than established commercial production, materials in this compositional space show promise for next-generation battery cathodes, supercapacitors, and catalytic electrodes where layered or tunneled structures enable sodium-ion diffusion.
