title: [Diphenyldi(pyrazol-1-yl)methane]-dinitratocobalt(II).
abstract: In the title compound, [Co(NO(3))(2)(C(19)H(16)N(4))], the diphenyl-dipyrazolylmethane ligand coordinates to Co(II) in a bidentate fashion forming a six-membered ring with an approximate boat configuration. The mean planes of the two pyrazolyl rings are separated by an angle of 39.6 (2)°. The coordination at the Co(II) center is best described as distorted octa-hedral with two NO(3) (-) anions serving as bidentate ligands for charge balance. The dihedral angle between the mean planes of the two nitrate rings is 85.0 (1)° and that between the mean planes of the two phenyl rings is 73.7 (1)°. The crystal structure is stabilized by weak inter-molecular C-H⋯O and intra-molecular C-H⋯N hydrogen-bond inter-actions.
