Abstract: The asymmetric unit of the title compound, [ZnI(C₈H₁₆N₄)]I₃, contains one iodido(1,4,7,10-tetraazacyclododecane)zinc(II) cation, with zinc in a slightly distorted square-pyramidal coordination geometry, and one triiodide counter-anion. The coordination number of zinc is five. In the cation, the iodine ion is located at the apex of the square pyramid and the zinc ion lies 0.846 (15) Å from the basal plane, which is made up of four N atoms. Weak intermolecular C-HI interactions seem to be effective in stabilizing the crystal structure.
