What is the coordination number of Pt in cisplatin?

Options

Correct answer

A. 4

Step-by-step solution

The coordination complex cisplatin has the chemical formula cis-[Pt(NH₃)₂Cl₂] , where platinum is the central metal atom coordinated to two ammonia ( NH₃ ) and two chloride ( Cl⁻ ) ligands. Each ligand is monodentate, donating one coordinate bond to the metal center. The total coordination number is therefore 2 + 2 = 4 . The correct option is A. 4
