Synthesis and crystal structure of catena-poly[tetra-μ-acetato-copper(II)]-μ-6-eth­­oxy-N2,N4-bis­­[2-(pyridin-2-yl)eth­yl]-1,3,5-triazine-2,4-di­amine]

The title compound, [Cu2(C19H23N7O)(C2H3O2)4]n, was obtained via reaction of copper(II) acetate with the coordinating ligand, 6-eth­oxy-N2,N4-bis­[2-(pyridin-2-yl)eth­yl]-1,3,5-triazine-2,4-di­amine. The crystallized product adopts the monoclinic P21/c space group. The metal core exhibits a paddle-wheel structure typical for dicopper tetra­acetate units, with triazine and pyridyl nitro­gen atoms from different ligands coordinating to the two axial positions of the paddle wheel in an asymmetric manner. This forms a coordination polymer with the segments of the polymer created by the c-glide of the P21/c setting of the space group. The resulting chains running along the c-axis direction are held together by intra­molecular N—H⋯O hydrogen bonding. These chains are further packed by dispersion forces, producing an extended three-dimensional structure.
