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.

WebIt is not the case that Z and cis or E and trans are always interchangeable. Consider the following fluoromethylpentene: The proper name for this molecule is either trans-2-fluoro-3-methylpent-2-ene because the alkyl groups that form the backbone chain (i.e., methyl and ethyl) reside across the double bond from each other, or (Z)-2-fluoro-3 ...
