title: [2,9-Bis(3,5-dimethyl-1H-pyrazol-1-yl-κN)-1,10-phenanthroline-κN,N'](methanol-κO)(nitrito-κO,O')cadmium(II) perchlorate.
abstract: In the title complex, [Cd(NO(2))(C(22)H(20)N(6))(CH(3)OH)]ClO(4), the Cd(II) ion is in a distorted penta-gonal-bipyramidal CdN(4)O(3) coordination geometry. The dihedral angles formed between the mean planes of the pyrazole rings and the phenanthroline ring system are 4.37 (19) and 5.84 (21)°. In the crystal, the anions and cations are connected by inter-molecular O-H⋯O hydrogen bonding, while pairs of weak inter-molecular C-H⋯O hydrogen bonds connect the cations into centrosymmetric dimers. In addition, there is a π-π stacking inter-action involving two symmetry-related benzene rings, with a centroid-centroid distance of 3.437 (3) Å.
