The key difference between inert and labile complexes is that inert complexes undergo slow substitution, whereas labile complexes undergo rapid substitution.
The terms inert complex and labile complex come under the category of transition metal complexes. A transition metal complex is an inorganic compound which has a transition metal atom or ion in the center of the complex, and there are two or more ligands attached to this metal center. We can classify these complexes into two groups as inert complexes and labile complexes, depending on the substitution reactions that they undergo.
