Chemistry and Biochemistry
In the title compound, [Co(NO3)2(C19H16N4)], the diphenyldipyrazolylmethane ligand coordinates to CoII 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 CoII center is best described as distorted octahedral with two NO3- 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 intermolecular C-HO and intramolecular C-HN hydrogen-bond interactions.
