ammonia and cyclohexylamine are neutral donors, whereas each coordinated chloride and acetate has charge

- 1

. Charge balance therefore gives Pt(II) in cisplatin and Pt(IV) in satraplatin:

x_{cisplatin} - 2 = 0, x_{satraplatin} - 2 - 2 = 0.

The two acetate groups count once each; their carbonyl and alkoxy oxygen atoms do not make each ligand doubly charged.
