Abstract: The hydrothermal reaction of ethylenediamine with CoCl₂·6H₂O yielded tris(ethylenediamine-²N,N')cobalt(III) chloride diiodide monohydrate, [Co(C₂H₈N₂)₃](Cl)(I)₂·H₂O, which consists of [Co(en)₃]³⁺ cations, Cl^- and I^- anions, and solvent water molecules. The Cl^- anions bridge the [Co(en)₃]³⁺ complexes to form two-dimensional honeycomb-like layers through N-HCl hydrogen bonds, which stack along the c direction to form channels hosting I^- ions and water molecules.
