The Solid-State Landscape of 4,4’-Azobis(3,5-dimethyl-1H-pyrazole) With the Isolation of Conformer-dependent Polymorphs

The molecule 4,4´-azobis(3,5-dimethyl-1H-pyrazole) (H2azbpz) can exist in different planar conformers which differ in the relative orientation of the NH atoms with respect to the central azo bond a...
