Crystal structure of tris­­(trans-1,2-di­amino­cyclo­hexane-κ2N,N′)cobalt(III) trichloride monohydrate

The synthesis of the title hydrated complex salt, [Co(C6H14N2)3]Cl3H2O, from racemic trans-1,2-diaminocyclohexane and [CoCl(NH3)5]Cl2 and its structural characterization are presented in this paper. The product was synthesized in the interest of understanding the hydrogen-bonding patterns of coordination complexes. Previous characterizations of the product in the I42d space group have not yielded coordinates; thus, this paper provides the first coordinates for this complex in this space group. The octahedrally coordinated cation adopts twofold rotation symmetry, with outer-sphere chloride counter-ions and solvent water molecules forming a hydrogen-bonded network with amine H atoms.
