Strategy:
 Heavy transition metals (4d and 5d series) like Platinum () almost exclusively form low-spin complexes regardless of the ligand, due to the very high crystal field splitting energy ().

Step 1: Determine the configuration of the metal
Primary valency (Oxidation state) of Pt in :
.
Platinum is in group 10 (), so  has a  configuration.

Step 2: Determine hybridization and magnetic moment
 forms a square planar complex ( hybridisation). The large crystal field splitting forces all 8 elec
