Question

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

Answer

Coordination number and oxidation state of the given compound is given as,

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
