· Na2 S4 Fe2

Na₂S₄Fe₂ is an iron-sulfur compound belonging to the polysulfide family, characterized by iron cations coordinated with sulfur chains. This material exists primarily in research and laboratory contexts rather than established commercial applications, with potential relevance to energy storage systems (particularly as a cathode material or sulfur chemistry precursor) and electrochemistry research exploring iron-sulfur redox chemistry.
