Answer: Cisplatin [cis-Pt(NH 3 ) 2 Cl 2 ].
- A Cisplatin [cis-Pt(NH<sub>3</sub>)<sub>2</sub>Cl<sub>2</sub>]
- B [Co(NH<sub>3</sub>)<sub>6</sub>]Cl3 in routine practice
- C [Fe(CN)<sub>6</sub>]4- overall in most cases
- D [Cu(NH<sub>3</sub>)4]2+ under typical conditions
Correct answer: A. Cisplatin [cis-Pt(NH<sub>3</sub>)<sub>2</sub>Cl<sub>2</sub>]
Explanation: Cisplatin (cis-diamminedichloroplatinum(II)) crosslinks DNA strands in cancer cells, inhibiting replication.
The three common coordination geometries: octahedral (6 ligands), tetrahedral (4 ligands), and square planar (4 ligands in one plane).
Concept context
