Chemistry - Coordination Chemistry Question with Solution | TestHub

Initial State: In the complex $[Pt(N{H}_3{)}_2(SCN{)}_2]$, $P{t}^{2+}$ has a $d^8$ configuration and forms a square planar complex with $ds{p}^2$ hybridization.

Ligand Replacement: The glycinato ligand ($gl{y}^{-}$) is an unsymmetrical bidentate ligand coordinating through one Nitrogen (N) and one Oxygen (O) atom.

Final State: Replacing two $N{H}_3$ molecules with one $gl{y}^{-}$ ligand yields $[Pt(gly)(SCN{)}_2]$, which remains a square planar complex with the same $ds{p}^2$ hybridization.

Why others change: The splitting energy changes due to the new O-donor atom, the number of Metal-Nitrogen linkages decreases from 2 to 1, and the unsymmetrical nature of glycinato alters the geometrical isomerism profile.
