Abstract

The title compound, [Ni(C6H24N6)][CdI4], contains two discrete ions, an [Ni(en)(3)](2+) (en = ethylenediamine) cation and a [CdI4](2-) anion. The Ni2+ ion is coordinated by three chelating ethylenediamine ligands in a distorted octahedral geometry while the Cd2+ ion binds four iodide ions in a slightly distorted tetrahedron. Both the Ni and Cd atoms lie on threefold axes of rotation. The structure is disordered at cadmium, with two alternative sites for the metal in a 97:3 ratio; the minor component of the disorder inverts the CdI4 tetrahedron and reverses the direction of propagation of the aligned [CdI4](n)(2-) units.
