One‐dimensional conductor : Strong π interactions between ecliptically stacked tellurium squares in Te 4 [Bi 0.74 Cl 4 ] trigger excellent one‐dimensional metallic conductivity as well as superconductivity below 7.15 K under ambient pressure. The electron‐precise counterpart, Te 4 [Bi 0.67 Cl 4 ], is a semiconductor. The bismuth content and temperature‐ dependent competition of intra‐ and inter‐ring bonding account for the electronic conduction.
