N2 - In the title compound, [Cu(C9H5N4O)Cl(C12H8N2)] n or [Cu(tcnoet)Cl(phen)] n , where phen is 1,10-phenanthroline and tcnoet is 1,1,3,3-tetra-cyano-2-eth- oxy-propenide, the axially elongated (4 + 2) coordination polyhedron around the CuII 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 C3O fragment.
