MCQ
The coordination of $Pt$ in the complex ion $\left[\mathrm{Pt}(\mathrm{en})_2 \mathrm{Cl}_2\right]^{2+}$ is:
  • A
    $3$
  • B
    $4$
  • C
    $5$
  • ✓
    $6$
✓

Answer

Correct option: D.
$6$
The coordination of $Pt$ in the complex ion $\left[\mathrm{Pt}(\mathrm{en})_2 \mathrm{Cl}_2\right]^{2+}$ is $6.$
$\text{en}\ ($ethylene diamine$)$ is bidentate ligand.
So$\text{, 2 en}$ ligands and $2Cl^-$ ligands corresponds to six donor atoms.
