The magnetic moment of an octahedral homoleptic Mn(II) complex is 5.9 BM. The suitable ligand for this complex is -
Multiple Choice Options
- A CN
- B ethylenediamine
- C NCS–
- D CO
Step-by-Step Verified Solution
Given, = 5.9 BM
n = number of unpaired electron = 5
For Mn+2 with 5 unpaired electronic configuration only possible when ligand is weak field ligand.
Here weak field ligand is NCS .
n = number of unpaired electron = 5
For Mn+2 with 5 unpaired electronic configuration only possible when ligand is weak field ligand.
Here weak field ligand is NCS .
