In the title compound, 2[Co(C(2)N(3))(NO(3))(C(14)H(12)N(2))(H(2)O)]·C(14)H(12)N(2)·2H(2)O, the Co(II) ion is coordinated by a bidentate 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand, a bidentate nitrate anion, a water mol-ecule and a monodentate dicyan-amide group in a distorted octa-hedral geometry. One uncoordinated dmphen mol-ecule is situated on a crystallographic twofold axis and the asymmetric unit is completed by one water mol-ecule. In the crystal, mol-ecules form a one-dimensional framework in the [001] direction through O-H⋯N and O-H⋯O hydrogen bonds. The crystal packing is further stabilized by π-π stacking inter-actions between the dmphen rings of neighboring mol-ecules, with a centroid-centroid separation of 3.5641 (8) Å and a partially overlapped arrangement of parallel dmphen rings with a distance of 3.407 (2) Å.
在标题化合物2[Co(C₂N₃)(NO₃)(C₁₄H₁₂N₂)(H₂O)]·C₁₄H₁₂N₂·2H₂O中，Co(II)离子由一个双齿的2,9-二甲基-1,10-菲咯啉（dmphen）配体、一个双齿硝酸根阴离子、一个水分子和一个单齿氰胺基团以扭曲的八面体几何构型配位。一个未配位的dmphen分子位于一个晶体学二重轴上，不对称单元由一个水分子补充完整。在晶体中，分子通过O-H⋯N和O-H⋯O氢键在[001]方向形成一维框架。相邻分子的dmphen环之间的π-π堆积相互作用进一步稳定了晶体堆积，质心间距为3.5641 (8) Å，平行dmphen环部分重叠排列，间距为3.407 (2) Å。
