the magnetic moment of cobalt in hg[co(scn4)]

In Hg[Co(SCN)4] complex, Cobalt is present as Co+2 which has 3d7, it means it has 3 unpaired electrons.

Magnetic moment μ = where, n = number of unpaired electrons

n = 3 for Co+2

μ =

=

= 3.99 B.M.

  • 34

Co3= d6s0   here 2 unpaired electron because of  strong legand 

  so  magnetic moment = root of n(n+2)

  root of 2(2+2)

  root 8

  =2.8284271
