The rigidity and chelation effect of ligands on the hydrogen evolution reaction catalyzed by Ni(ii) complexes

Abstract

With increasing interest in nickel-based electrocatalysts, three heteroleptic Ni(II) dithiolate complexes with the general formula [Ni(II)L(L’)2] (1-3), L= 2-(methylene-1,1’-dithiolato)-5,5’-dimethylcyclohexane-1,3-dione; and L’ = triphenylphosphine (1), 1,2-bis(diphenylphosphine)ferrocene (DPPF) (2), 1,2-bis(diphenylphosphine)ethane (DPPE) (3)...

Unravelling the kinetics of electro- and photochemical S → O linkage isomerization in Ru(ii)–NHC–DMSO complexes utilised for photoinduced substitution reactions

“…The chemistry of ruthenium-DMSO complexes has attracted considerable attention, particularly among other Ru complexes, owing to their diverse applications across various fields. 1–14 Because of the labile nature of DMSO ligands, these complexes can readily undergo substitution and become compatible with physiological conditions, which is essential for biomedical applications. 15–19 Other pivotal roles of these complexes have also been explored and include application as suitable precursors 4,20–26 for the generation of subsequent derivatives having aqua, 27,28 nitrosyl, 29–31 carbonyl, 32 polypyridine, 33 and other aromatic ligands.…”
