【 摘 要 】

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 π-bonded dimeric entities by a stacking contact involving symmetry-related phenyl rings, with a centroid–centroid distance of 3.468 (3) Å and a slippage of 0.951 Å. The dimers are, in addition, sustained by a number of C—H⋯I and I⋯π (I⋯centroid = 3.876 Å) inter­actions involving the anion. Finally, inter­dimeric contacts are of the C—H⋯I and C—H⋯π types.
