Synthesis and structure determination of racemic (Δ/Λ)-tris­(ethyl­enedi­amine)­cobalt(III) trichloride hemi(hexa­aqua­sodium chloride)

The synthesis and crystal structure of the title racemic compound, [Co(C(2)H(8)N(2))(3)]Cl(3).{[Na(H(2)O)(6)]Cl}(0.5), are reported. The trivalent cobalt atom, which resides on a crystallographic threefold axis, is chelated by a single ethyl­ene di­amine (en) ligand and yields the tris-chelate [Co(en)(3)](3+) cation with distorted octa­hedral geometry after the application of crystal symmetry. The sodium cation (site symmetry [Image: see text]), has a single water mol­ecule bound to it in the asymmetric unit and yields a distorted, octa­hedrally coordinated hydrated [Na(H(2)O)(6)](+) cation after the application of symmetry. One of the chloride ions lies on a general position and the other has [Image: see text] site symmetry. An extensive array of C—H⋯O, N—H⋯Cl and O—H⋯Cl hydrogen bonds exists between the ethyl­ene di­amine ligands, the water mol­ecules of hydration, and the anions present, thereby furnishing solid-state stability.
