· Er2 Cu1 Ru1

Er₂Cu₁Ru₁ is an intermetallic compound combining erbium (a rare-earth element), copper, and ruthenium in a 2:1:1 stoichiometric ratio. This ternary compound is primarily of research interest rather than established commercial production, studied for its potential in thermoelectric, magnetic, and electronic applications where the rare-earth element's f-electron behavior combined with transition metal properties could offer unique functional characteristics.
