Q3 of 26 Page 1

Write the coordination number and oxidation state of Platinum in the complex [Pt (en)2Cl2 ].

Given Complex Compound

[Pt (en)2Cl2]


Coordination no. = denticity × number of ligand


Coordination number = 2 × 2 + 2 × 1 = 6


Charge on ligand + O.S. of metal ion = charge on complex– 2 + x = 0


x = +2
