Abstract: In the title complex, [Cu₂Br₂(C₁₄H₁₁N₅)]_n, there are two crystallographically independent Cu^I cations with different coordination geometries: one has tetrahedral geometry (CuBr₂N₂), and the other adopts a trigonal geometry (CuBr₂N). The 2-amino-4-(2-pyridyl)-6-(4-pyridyl)pyrimidine (appm) ligand acts as a bridging ligand. Four Br^- anions connect four Cu^I cations to form an eight-membered ring, and the appm ligands link adjacent eight-membered rings to construct a one-dimensional ribbon chain.
