Abstract :
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.
