In this talk, we will describe synthetic mono- and multi-nuclear iron complexes that react with O2 within single crystalline matrices. Structural and spectroscopic analyses of these systems reveal high-spin iron centers that act cooperatively to mediate O-O bond activation and rupture. These processes can be monitored in unprecedented detail and, as such, may lend critical insight into O2 activation processes accomplished by natural mono- and dioxygenase systems.
