Question
′Spin only′ magnetic moment of Ni in [Ni(dmg)2] is same as that found in :
Options
A.Ni in [NiCl2 (PPh3)2]
B.Mn in [MnO4]-
C.Co in [CoBr4]2-
D.Pt in [Pt (H2O)2 Br2]
Solution
Ni (dmg)2 complex is square planar and dimagnetic.
(B) Mn in [MnO4]- is in + 7 oxidation state having [Ar]18 3d0 configuration. Complex ion is tetrahedral and diamagnetic
(D) Pt (II) - 5d8 configuration. Complex is square planar and therefore, dimagnetic.
So, μ= 0
