| Sumario: | The molecular geometry of the ionic title compound, C14H17N4 + I or DAZOP+ I , is essentially featureless. Regarding the crystal structure, in addition to the obvious cation–anion Coulombic interactions, the packing is mostly directed by non-covalent interactions involving both ring systems, as well as the iodide anion. It consists of cationic molecules aligned along [101] and disposed in an antiparallel fashion while linked into -bonded dimeric entities by a stacking contact involving symmetry-related phenyl rings, with a centroid–centroid distance of 3.468 (3) A˚ and a slippage of 0.951 A˚ . The dimers are, in addition, sustained by a number of C—HI and I (Icentroid = 3.876 A˚ ) interactions involving the anion. Finally, interdimeric contacts are of the C—HI and C—H types.
