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-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 C3O fragment.
在标题化合物[Cu(C₉H₅N₄O)Cl(C₁₂H₈N₂)]ₙ或[Cu(tcnoet)Cl(phen)]ₙ中，其中phen为1,10 - 菲咯啉，tcnoet为1,1,3,3 - 四氰基 - 2 - 乙氧基丙烯腈，Cu(II)中心周围轴向拉长的(4 + 2)配位多面体包含来自三个不同tcnoet配体的N原子。所得的配位聚合物呈片状，通过单个C - H...N氢键成对连接形成双层。键长为phen配体中显著的键固定和tcnoet配体中广泛的电子离域提供了证据，其中两个 -C(CN)₂单元以对旋方式旋转出中心C₃O片段的平面。
