· Li4 Fe2 As2 C2 O14

Li₄Fe₂As₂C₂O₁₄ is an experimental mixed-anion compound combining lithium, iron, arsenic, carbon, and oxygen in a complex crystal structure; it belongs to the broader family of polyanion-based materials being explored for advanced electrochemical applications. While not yet in commercial production, compounds of this type are of research interest in energy storage and solid-state battery development, where the multi-component anion framework can provide structural stability and tunable electrochemical behavior compared to simpler oxide cathodes. The specific combination of arsenic and carbon-based ligands in a lithium-iron matrix represents an uncommon structural motif that may offer advantages in ionic conductivity or cycling stability, though practical viability remains under investigation.
