title: Aqua-(dicyanamido-κN)(2,9-dimethyl-1,10-phenanthroline-κN,N')(nitrato-κO,O')cobalt(II)-2,9-dimethyl-1,10-phenanthroline-water (2/1/2).
abstract: 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.
