WebIn cis molecules, the two ligands are on the same side of the complex. This means that in both octahedral and square planar complexes the bond angle between the two similar ligands will be 90 degrees. In trans molecules, the similar ligands are on the opposite sides of the molecules, meaning the bond angle is 180 degrees.
