Addition of excess aqueous ammonia to a pink coloured aqueous solution of

M C l_{2} . 6 H_{2} O (X)

and

N H_{4} C l

gives an octahedral complex Y in the presence of air. In aqueous solution, complex Y behaves as 1 : 3 electrolyte. The reaction of X with excess HCl at room temperature results in the formation of a blue coloured complex Z. The calculated spin only magnetic moment of X and Z is 3.87 B.M., whereas it is zero for complex Y.
