One mole of the octahedral complex compound $\displaystyle \mathrm{Co}\left(\mathrm{NH}_3\right)_5 \mathrm{Cl}_3$ gives $\displaystyle 3$ moles of ions on dissolution in water. One mole of the same complex reacts with excess of $\displaystyle \mathrm{AgNO}_3$ solution to yield two moles of $\displaystyle \mathrm{AgCl}_{(\mathrm{s})}$. The structure of the complex is:
