Edge-sharing rhombic [Cu2Te2] units form the building blocks in the corrugated anionic [Cu5Te5] layers (see the sketch at the right) in mixed-valent K2Cu5Te5—a metallic conductor of the p type. K2Cu5Te5 is formed on treatment of Cu with K2Tex (x ≈ 4) at 350°C in vacuum as black crystals and is stable to air and moisture.
