Strategy:
 First, solve for 'n' which is the total geometrical isomers for a square planar complex bearing 4 distinct ligands. Then evaluate the specified Iron complex for magnetic moment and CFSE.

Step 1: Find 'n'
 is a square planar complex with four completely different monodentate ligands ().
By fixing one ligand in space and substituting the others trans to it, we generate exactly 3 distinct geometrical isomers. Thus, .

Step 2: Formulate the Iron complex
The target is .
Substituting  give
