Question

5 The values of the spin only magnetic moments (uso)of several complexes are given below. Show how these values of uso are consistent with the structure of each complex. (a) uso = 2.83 for [Ni(OH2).]2+ (b) uso = 0 for [Ni(CO)4] (c) Mso = 1.73 for [Cu(NH3)6]2+ (d) uso = 3.88 for (Co(OH2)6]2 (e) uso = 5.92 for [Fe(OHz)o]** and [Mn(Br)]2
