Catena-Poly[[[4-amino-3,5-bis(pyridin-2-yl)-4H-1,2,4-triazole-κ2N1,N5](dicyanamido-κN)copper(II)]-μ2-dicyanamido-κ2N:N'] : coordination polymer chains linked into a bilayer by hydrogen bonds and π-π Stacking interactions
Abstract
In the title compound, [Cu(C2N3)2(C12H10N6)]n or [Cu(dca)2(abpt)]n, where abpt is 4-amino-3,5-bis(pyridin-2-yl)-H-1,2,4-triazole and dca is the dicyanamide anion, the CuII 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 μ1,5-bridging ligand between pairs of CuII 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 CuII complexes containing dca ligands and heteroaromatic co-ligands.
