Electronic configuration of Cu2+ ion in [Cu(NH3)4]2+.
Cu2+ ion =[Ar]3d94s0.
∴Cu2+ ion has one unpaired electron.
Magnetic moment of [Cu(NH3)4]2+(μ)=n(n+2)BM
where, n=no. of unpaired electrons
μ = √1(1+2) = √3 = 1.73BM
Whereas Ni2+ in [Ni(CN)4]2−,Ti4+ in TiCl4 and Co2+ ion [COCl6]4− has 2,0 and 3 unpaired electrons respectively.
