The chemical formula for tris(ethylenediamine)cobalt(III) chloride is \([Co(en)_3]Cl_3\), where "en" represents ethylenediamine (C₂H₈N₂).
In this formula, cobalt is in the +3 oxidation state, and it is coordinated to three ethylenediamine ligands. The coordination sphere is represented as \([Co(en)_3]^{3+}\), indicating that cobalt is surrounded by three bidentate ligands (each ethylenediamine can coordinate through its two nitrogen atoms).
Thus, the notation for the coordination sphere of this complex is \([Co(en)_3]^{3+}\).
