Question

The structure of the complex $\left[Pt\right(N{H}_3{)}_4{]}^{2+}$ is:

• A. Square planar
• B. Tetrahedral
• C. Pyramidal
• D. Pentagonal

Answer 1

The correct option is A Square planar

$\left[Pt\right(N{H}_3{)}_4{]}^{2+}\text{Valence shell electronic configuration of}P{t}^{2+}\to \left[Xe\right]4f^{14}5d^{8}6s^{0}6p^0$


$N{H}_3$ is a strong field ligand. So all unpaired electrons get paired.


$\text{Hybridisation}=ds{p}^2\text{Structure = Square planar}$
