Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>In the title compound, [Cu(C₂N₃)₂(C₁₂H₁₀N₆)]_{<italic>n</italic>} or [Cu(dca)₂(abpt)]_{<italic>n</italic>}, where abpt is 4‐amino‐3, 5‐bis(pyridin‐2‐yl)‐4<italic>H</italic>‐1, 2, 4‐triazole and dca is the dicyanamide anion, the Cu^II centre is five‐coordinate with an approximately square‐pyramidal geometry. One of the two dicyanamide ligands is a terminal ligand, but the other one acts as a μ_{1, 5}‐bridging ligand between pairs of Cu^II centres, so generating a one‐dimensional coordination polymer. A combination of N—H...N and C—H...N hydrogen bonds, augmented by π–π stacking interactions, links the coordination polymer chains into a bilayer structure. Comparisons are made with some related Cu^II complexes containing dca ligands and heteroaromatic co‐ligands.</p> </abstract>
