Cisplatin molecules bind to nitrogen atoms

WebIn the cisplatin molecule, the atoms H, Cl, N, and Pt are involved in bonds. H is bonded with N, Pt is bonded with B, and Pt is bonded with Cl. The eletronegativity values for these atoms are as follows: hydrogen (H) is 2.2, nitrogen (N) is 3, platinum (Pt) is 2.3, and Chlorine (Cl) in 3.2.
