A transition metal oxo complex is a coordination complex containing an oxo ligand. Formally O2-, an oxo ligand can be bound to one or more metal centers, i.e. it can exist as a terminal or (most commonly) as bridging ligands (Fig. 1). Oxo ligands stabilize high oxidation states of a metal. They are also found in several metalloproteins, for example in molybdenum cofactors and in many iron-containing enzymes. One of the earliest synthetic compounds to incorporate an oxo ligand is potassium ferrate (K2FeO4), which was likely prepared by Georg E. Stahl in 1702.

- Un complexe oxo est un complexe métallique dont un ligand est l'anion bidenté oxyde O2−, généralement pontant, parfois terminal. Ce ligand stabilise les états d'oxydation élevés des cations métalliques. On le trouve dans diverses métalloprotéines, comme les cofacteurs molybdoptérine et FeMoco (« cofacteur à fer et molybdène »), ainsi que dans de nombreuses enzymes contenant du fer. L'un des premiers composés synthétiques contenant un ligand oxo est sans doute le ferrate de potassium K2FeO4, probablement préparé par le chimiste allemand Georg Ernst Stahl dès 1702. (fr)
