The title complex, [Cu(C 6 H 4 N 3 )] n , was synthesized by the reaction of cupric nitrate, 1 H ‐benzotriazole (BTAH) and aqueous ammonia under hydrothermal conditions. The asymmetric unit contains three crystallographically independent Cu I cations and two 1 H ‐benzotriazolate ligands. Two of the Cu I cations, one with a linear two‐coordinated geometry and one with a four‐coordinated tetrahedral geometry, are located on sites with crystallographically imposed twofold symmetry. The third Cu I cation, with a planar three‐coordinated geometry, is on a general position. Two Cu I cations are doubly bridged by two BTA − ligands to afford a noncentrosymmetric planar [Cu 2 (BTA) 2 ] subunit, and two [Cu 2 (BTA) 2 ] subunits are arranged in an antiparallel manner to form a centrosymmetric [Cu 2 (BTA) 2 ] 2 secondary building unit (SBU). The SBUs are connected in a crosswise manner via the sharing of four‐coordinated Cu I cations, Cu—N bonding and bridging by two‐coordinate Cu I cations, resulting in a one‐dimensional chain along the c axis. These one‐dimensional chains are further linked by C—H...π and weak van der Waals interactions to form a three‐dimensional supramolecular architecture.
