A pink solid has the formula CoCl₃.5NH₃.H₂O. A solution of this salt is also pink and rapidly gives 3 mol AgCl on titration with silver nitrate solution. When the pink solid is heated, it loses 1 mol H₂O to give a purple solid with the same ratio of NH₃:Cl:Co. The purple solid, on dissolution and titration with AgNO₃, releases two of its chlorides rapidly. Deduce the structures of the two octahedral complexes and draw and name them.
