An elusive S =3/2 oxocobalt(IV) complex is stabilized by a Lewis acid interaction with a scandium(III) ion. The {Co IV ‐O‐Sc} 3+ unit, characterized by spectroscopic and DFT methods, is a stronger electron‐transfer and H‐atom abstraction agent but weaker oxo‐transfer agent than the corresponding {Fe IV O} complex (see scheme; L=tris[2‐( N ‐tetramethylguanidyl)ethyl]amine).
