Abstract: | The crystal structure of catena‐poly[[[acetato(1,10‐phenanthroline‐κ2N,N′)copper(II)]‐μ‐dicyanamido‐κ2N1:N5] trihydrate], {[Cu(C2H3O2)(C2N3)(C12H8N2)]·3H2O}n, consists of a zigzag chain formed by the polymer [Cu(CH3COO)(dca)(phen)]n (phen is 1,10‐phenanthroline and dca is dicyanamide), with three water molecules per repeat unit of the polymer. The CuII atom has a slightly distorted square‐pyramidal coordination environment consisting of two N atoms of the phen ligand, two nitrile N atoms of different dca ligands, one of them axial, and one O atom of the acetate anion. The compound forms a one‐dimensional chain using dca as an end‐to‐end bridging ligand. Non‐covalent interactions, π–π stacking and hydrogen bonding mediate the bundling of the polymer chains into a three‐dimensional structure, with the water molecules playing an important role in the hydrogen bonding. |
