Abstract

Abstract : An electrocatalytically active cobalt diimine dioximate metalloligand was prepared and explored as a precursor for a variety of multimetallic complexes with Co–Zn, –Cd, –Mn, and –Ru coordination. Abstract : An electrocatalytically active cobalt diimine monoxime monoximate complex was deprotonated by 1-methylimidazole affording a doubly deprotonated complex that serves as a versatile precursor for synthesis of a variety of multimetallic complexes with Co–Zn, –Cd, –Mn and –Ru coordination. These complexes were studied using a combination of spectroscopic, analytical and electrochemical techniques, revealing the electronic and structural parameters unique to this new class of compounds. The ability of these complexes to catalyze proton reduction was also investigated. These complexes are homogeneous electrocatalysts for the hydrogen evolution reaction through reduction of [NEt3 H][BPh4 ] in CH3 CN, however decompose under extended electrolysis conditions.
