Strategy:
 Count the number of diamagnetic complexes from the provided list to find 'n'. Determine which of the listed metals has the lowest enthalpy of atomization, and calculate the magnetic moment for .

Step 1: Find 'n' (Count diamagnetic complexes)
- : Tetrahedral  (). High spin, 2 unpaired. (Paramagnetic)
- : Octahedral  (). Fully paired. (Diamagnetic)
- : Octahedral  (). Low spin , 2 unpaired. (Paramagnetic)
- : Contains  (). Fully paired. (Diamagnetic)
Number of diamagnetic complexes, th
