Cooperative redox and spin activity from three redox congeners of sulfur-bridged iron nitrosyl and nickel dithiolene complexes.

ABSTRACT: The synthesis of sulfur-bridged Fe-Ni heterobimetallics was inspired by Nature's strategies to "trick" abundant first row transition metals into enabling 2-electron processes: redox-active ligands (including pendant iron-sulfur clusters) and proximal metals. Our design to have redox-active ligands on each metal, NO on iron and dithiolene on nickel, resulted in the observation of unexpectedly intricate physical properties. The metallodithiolate, (NO)Fe(N₂S₂), reacts with a labile ligand derivative of [Ni^II(S₂C₂Ph₂)]⁰, Ni_DT, yielding the expected S-bridged neutral adduct, FeNi, containing a doublet {Fe(NO)}⁷. Good reversibility of two redox events of FeNi led to isolation of reduc
