In the title polymer, Cd(C(2)N(3))(2)(C(16)H(16)N(2)O(2)), the Cd(II) ion is coordinated by two N atoms from one 2,9-dieth-oxy-1,10-phenanthroline mol-ecule and four N atoms from four symmetry-related dicyanamide ions in a distorted octa-hedral geometry. In the 2,9-dieth-oxy-1,10-phenanthroline ligand, the O and C atoms of the eth-oxy groups are located almost in the plane defined by the phenanthroline ring system. Two dicyanamide ions bridge two Cd(II) ions, which are located on a twofold axis, forming a one-dimensional zigzag chain along the [001] direction. The 2,9-dieth-oxy-1,10-phenanthroline mol-ecules act as bidentate terminal ligands. There are π-π inter-actions between polymeric chains, characterized by a centroid-centroid distance of 3.7624 (2) Å between the phenanthroline rings of two neighbouring chains.
在标题聚合物[Cd(C₂N₃)₂(C₁₆H₁₆N₂O₂)]ₙ中，Cd(II)离子由一个2,9 - 二乙氧基 - 1,10 - 菲咯啉分子中的两个N原子和四个来自四个对称相关双氰胺离子的N原子配位，形成扭曲的八面体几何构型。在2,9 - 二乙氧基 - 1,10 - 菲咯啉配体中，乙氧基的O和C原子几乎位于由菲咯啉环系所定义的平面内。两个双氰胺离子桥连两个位于二重轴上的Cd(II)离子，沿[001]方向形成一维锯齿链。2,9 - 二乙氧基 - 1,10 - 菲咯啉分子作为双齿端基配体。聚合物链之间存在π - π相互作用，其特征是两个相邻链的菲咯啉环之间的质心 - 质心距离为3.7624 (2) Å。
