Abstract: The crystal structure of the title compound, [CuI(C₁₀H₈N₂)₂]I₃, has been reported previously [Freckmann & Tebbe (1981), Acta Cryst. A37, C-228], but full results were not published. The cation and anion possess crystallographically imposed C₂ and C_i symmetry, respectively. The Cu^II atom is coordinated by four N atoms of two bidentate 2,2'-bipyridine ligands and one I atom in a distorted trigonal-bipyramidal geometry. The I atom occupies an equatorial position. In the crystal packing, the aryl rings of adjacent bipyridine ligands stack along the c axis to form zigzag chains, with CC and CN separations in the range 3.365-3.713 Å.
