Edge‐sharing rhombic [Cu 2 Te 2 ] units form the building blocks in the corrugated anionic [Cu 5 Te 5 ] n 2n−layers (see the sketch at the right) in mixed‐valent K 2 Cu 5 Te 5 —a metallic conductor of the p type. K 2 Cu 5 Te 5 is formed on treatment of Cu with K 2 Te x (x ≈ 4) at 350°C in vacuum as black crystals and is stable to air and moisture.
