Oxo-Mo(IV) dithiolene complexes can reduce N/S-oxides and such complexes have been investigated as potential models for pterin containing molybdoenzymes. In general, Mo centers are coordinated by the same ligands creating a C4Vlocal symmetry about the first coordination sphere (MoOS4core) of molybdenum. We are interested in developing systems with a MoOS4core and C4Vlocal symmetry with dithiolene ligands being of extreme ends of the oxidation states. Such systems more accurately mimic the Mo-centers in complex iron-sulfur molybdoenzymes (CISM). We will discuss the synthesis, structure and reactivity of complexes with a MoOS4core . This presentation will focus on the differential reactivity observed in these systems.
