Bimetallic iron-iron and iron-zinc complexes of the redox-active ONO pincer ligand.

ABSTRACT: A new bimetallic platform comprising a six-coordinate Fe(ONO)₂ unit bound to an (ONO)M (M = Fe, Zn) has been discovered ((ONO^cat)H₃ = bis(3,5-di-tert-butyl-2-phenol)amine). Reaction of Fe(ONO)₂ with either (ONO^cat)Fe(py)₃ or with (ONO^q)FeCl₂ under reducing conditions led to the formation of the bimetallic complex Fe₂(ONO)₃, which includes unique five- and six-coordinate iron centers. Similarly, the reaction of Fe(ONO)₂ with the new synthon (ONO^sq˙)Zn(py)₂ led to the formation of the heterobimetallic complex FeZn(ONO)₃, with a six-coordinate iron center and a five-coordinate zinc center. Both bimetallic complexes were characterized
