Abstract: | The isotypic compounds tris(1,2‐ethanediamine‐N,N′)zinc(II) triiodide iodide, Zn(C2H8N2)3](I3)I, and tris(1,2‐ethanediamine‐N,N′)nickel(II) triiodide iodide, Ni(C2H8N2)3](I3)I, contain the octahedral M(en)3]2+ cation, with M = Zn and Ni, in both enantiomeric forms, an essentially linear triiodide anion and an iodide anion. The geometries of the complex ions are as expected, e.g.d(Ni—N) = 2.123 (5), 2.127 (6) and 2.134 (5) Å, and d(Zn—N) = 2.176 (4), 2.193 (4) and 2.210 (4) Å. The shortest contact between the triiodide and iodide ions is 3.979 (1) Å for the nickel compound and 4.013 (1) Å for the zinc compound. |
