Strategy:
 Given , we form a low-spin configuration regardless of the ligand, which is also characteristic of all 4d/5d transition metals like Ruthenium.

Step 1: Identify metal state
 contains .
Ruthenium is directly under Iron in group 8. Neutral Ru is , so  has a  configuration.

Step 2: Distribute electrons
Because , it forms a low-spin complex.
All 6 electrons occupy the lower orbitals: .
Unpaired electrons = 0.
Magnetic moment () = 0 BM.
