WebDrawbacks of the valence bond theory: a) Does not explain the colour exhibited by coordination compounds. b) Does not provide a quantitative interpretation of the stability of the complexes. c) Does not give the quantitative interpretation of magnetic data. WebWerner proposed the structure [Co (NH 3) 6 ]Cl 3, with the Co 3+ ion surrounded by six NH 3 at the vertices of an octahedron. The three Cl − are dissociated as free ions, which Werner confirmed by measuring the conductivity of the compound in aqueous solution, and also by chloride anion analysis using precipitation with silver nitrate.
