μ = 5.9 BM ∴ n (no of unpaired.e-) = 5 Cation MnII - 3d5 confn only possible for relatively weak ligand. ∴ NCS-

Q. The magnetic moment of an octahedral homoleptic Mn(II) complex is $5.9 BM$ . The suitable ligand for this complex is :

$C N^{-}$

$NC S^{-}$

$CO$

$μ = 5.9 BM ∴ n$ (no of unpaired.e-) = 5
Cation $M n^{II} - 3 d^{5}$ confn only possible for relatively weak ligand.
$∴$ $NC S^{-}$
