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. WebAug 6, 2011 · Cis/trans is for comparing only two non H groups, one on each side of the double bond. E/Z is when you have three or four non H groups. For E/Z, compare the atoms to each other on each side of the double bond: R1 R2 = R3 R4 Compare R1 vs. R2 and R3 vs. R4. Again priority is done by atomic weight.
