Abstract
The title compound, [Ni(C2H8N2)3]I2, crystallizes with an [Ni(en)3 2+] cation (en is ethane-1,2-diamine) and two iodide ions in the asymmetric unit. Two of the en ligands surrrounding the Ni2+ ion have disordered C atoms, while the third exhibits extensive weak N—H⋯I interactions with the two iodide ions that extend throughout the crystalline lattice, producing an infinite network along (011).
