Transition elements form complexes. (a) Molybdenum, Mo, forms an octahedral complex consisting of one Mo atom surrounded by carbon monoxide, CO, molecules. CO is a monodentate ligand. Iron forms an octahedral complex consisting of one Fe³⁺ and a number of cyanide, CN⁻, ions. CN⁻ is a monodentate ligand. [Figure not explicitly referenced, but implied for drawing in (a)(iii)]
