This is commonly seen in octahedral complexes with different types of ligands. For example, complexes like [CrCl3(py)]3 and [CrCl2(ox)2]3- may exhibit geometric and optical isomerism depending on the arrangement of ligands. Stereoisomers in [CrCl3(py)]3: In [CrCl3(py)]3, the complex is octahedral with three chloride ions and three pyridine molecules. Since pyridine is a monodentate ligand, there can be geometric isomerism based on how the chloride ions and pyridine molecules are arranged. There are two possible configurations, cis and trans, giving rise to stereoisomerism. In this case, there are a total of 3 stereoisomers. Stereoisomers in [CrCl2(ox)2]3-: In the case of [CrCl2(ox)2]3-, the complex contains two oxalate ligands, which are bidentate and can form chelate rings. The bidentate nature of oxalate introduces possibilities for cis and trans isomerism, depending on how the chloride and oxalate ions are positioned. In this case, there are 2 stereoisomers for the complex.
