WebCis form, when the same ligands are together Trans form, when the same ligands are opposite each other Explanation of the forms The cis form of platin is an anti cancer drug. It is believed to bind to DNA in cancer cells and prevent further cell … WebEarlier we looked at cis- and trans-isomers in square planar platinum complexes. Other transition metal complexes display cis-trans isomerism. Octahedral complexes can also have two particular ligands adjacent to each other or on opposite sides of the metal atom. For example, the cation [ (NH 3) 4 CoCl 2] + has a cis-isomer and a trans-isomer.
