WebWhen two compounds contain the same ligands coordinated to the same central ion, but the arrangement of ligands in the space is different, the two compounds are said to be stereoisomers and the type of isomerism is called stereoisomerism. Geometrical isomerism is due to ligands occupying different positions around the central metal ion.
