Strategy:
 Using identical ligands (), thermodynamic stability tracks with the magnitude of Crystal Field Stabilization Energy (CFSE). Compute and rank the absolute CFSE values.

Step 1: Calculate CFSE for low-spin states via 
- (I) :  (). Low-spin .
  CFSE = .
- (II) :  (). Low-spin .
  CFSE = .
- (III) :  (). Low-spin .
  CFSE = . (Maximum possible).
- (IV) :  (). Low-spin .
  CFSE = .

Step 2: Rank strictly by increasing stabilization (CFSE magnitude)
Order from least stabilization to most st
