WebOct 4, 2024 · In an octahedral complex, the two donor atoms in a bidentate ligand bind cis to each other. They can't reach all the way around the molecule to bind trans to each other. The spatial relationship between the metal and the two atoms connected to it from the same ligand forms a plane. WebMetal complexes that differ only in which ligands are adjacent to one another ( cis) or directly across from one another ( trans) in the coordination sphere of the metal are called geometrical isomers. They are most important for square planar and octahedral complexes.
