1. Cisplatin
Cisplatin is a compound from four ligands – two chlorine atoms and two amine molecules – that are covalently bonded to a central metal ion, which is platinum. This compound has a square planar shape with two similar ligands on one side; that is, the two chloride ions are on the same side of the square. This inorganic compound is currently being used to treat cancer due to its capability to adversely affect the replication process of the cancer cells’ DNA molecules. Accordingly, under aqueous environments, the chloride ligands are readily replaced by water molecules to reduce the stearic
