What is Inner Orbital Complex?

An inner orbital complex is a coordination compound in which the ligands cause hybridization that uses inner d-orbitals (n-1)d in addition to the ns and np orbitals of the central metal atom. These complexes are typically low-spin, diamagnetic (or have fewer unpaired electrons), and are associated with strong-field ligands such as CN⁻ and CO. The use of inner orbitals results in shorter, stronger metal-ligand bonds compared to outer orbital complexes.
