Abstract
In the title complex, [Cd(NO2)(C22H20N6)(CH3OH)]ClO4, the CdII ion is in a distorted pentagonal–bipyramidal CdN4O3 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 intermolecular O—H⋯O hydrogen bonding, while pairs of weak intermolecular C—H⋯O hydrogen bonds connect the cations into centrosymmetric dimers. In addition, there is a π–π stacking interaction involving two symmetry-related benzene rings, with a centroid–centroid distance of 3.437 (3) Å.
