· Co3S4

Co₃S₄ is a cobalt sulfide compound that exists as a mixed-valence spinel structure, combining cobalt in both +2 and +3 oxidation states. It is primarily investigated in electrochemistry and materials research rather than as an established structural material, with growing interest in energy storage and catalytic applications where its electronic and surface properties offer advantages in reaction kinetics and charge transfer.
