In the title compound, [Cu(C 9 H 5 N 4 O)Cl(C 12 H 8 N 2 )] n or [Cu(tcnoet)Cl(phen)] n , where phen is 1,10‐phenanthroline and tcnoet is 1,1,3,3‐tetracyano‐2‐ethoxypropenide, the axially elongated (4 + 2) coordination polyhedron around the Cu II centre contains N atoms from three different tcnoet ligands. The resulting coordination polymer takes the form of sheets which are linked in pairs by a single C—H...N hydrogen bond to form bilayers. The bond lengths provide evidence for significant bond fixation in the phen ligand and extensive electronic delocalization in the tcnoet ligand, where the two –C(CN) 2 units are rotated, in conrotatory fashion, out of the plane of the central C 3 O fragment.
