Cisplatin ligand substitution equation
WebThe main equilibrium involved in the ligand exchange reaction is: [Cu (H_2O)_6]^ {2+} + 4NH_3 \xrightleftharpoons {} [Cu (NH_3)_4 (H_2O)_2]^ {2+} + 4H_2O [C u(H 2O)6]2+ + 4N H 3 [C u(N H 3)4(H 2O)2]2+ + 4H 2O The colour of the deep blue complex is so strong that this reaction is used as a sensitive test for copper (II) ions in solution. Web(a) The structure of cisplatin (with platinum shown in green and nitrogen ligands shown in blue) coordinated to a dinucleotide containing two guanines. Notice the destacking of guanine bases, which would normally be parallel to one another. (b) The structure of cisplatin coordinated to two guanines in a DNA duplex. Reprinted with permission.1
