Co₂NiSe₄ is a quaternary metal selenide compound combining cobalt, nickel, and selenium in a fixed stoichiometric ratio, belonging to the chalcogenide family of materials. This is primarily a research-phase compound studied for its potential in thermoelectric and optoelectronic applications, where the mixed-metal selenide structure offers tunable electronic properties and moderate mechanical stiffness. The Co-Ni-Se system is of particular interest in materials research for energy conversion devices and solid-state electronics where layered or structured selenides can provide improved performance over single-element alternatives.
