Figure 1 . Molecular structure of the title compound, C6H24N6NiI2, showing the [Ni(en)32+] cation and two I_ ions in the asymmetric unit, the atom labeling scheme and 50% probability displacement ellipsoids. Only the major components of disordered carbon atoms (C11A, C12A & C21A, C22A) in rings 11 (Ni—N11—C11A—C12A—N12: 0.744 (12)) and 21 (Ni—N21—C21A—C22A—N22; 0.684 (9)) are depicted. Dashed lines indicate weak N—H⋯I hydrogen bond interactions. |
