Three pyridyl-amide substituted (benz)imidazolium salts H2L1Cl, H2L2Cl and H2L3Cl were synthesized and successfully employed as ligand precursors for the syntheses of novel nickel(II) and cobalt(III) complexes. The compounds H2L1Cl and H2L2Cl are precursors to tetradentate ligands and differ in the nature of the N-heterocyclic carbene (NHC) functionality, being imidazole-based and benzimidazole-based, resp. The ligand precursor H2L3Cl resembles H2L1Cl, but with one of the pyridyl groups replaced with a benzyl group, thus yielding a potential tridentate ligand. The nickel(II) compounds [Ni(L1)]Cl and [Ni(L2)]PF6 were obtained, bearing tetradentate ligands comprising an amidate and two pyridine nitrogen donor atoms and an (NHC) carbon donor. Single crystal x-ray crystallog. revealed that the nickel ions in both compounds are in slightly distorted square-planar geometries. Reactions of cobalt salts with the ligands H2L1Cl and H2L3Cl resulted in the cobalt(III) compounds [Co(L1)2]Cl and [Co(L3)2]PF6; the cobalt ions in both complexes are in octahedral geometries, bound by two tridentate ligands in a meridional binding mode, with two dangling pyridine and benzyl groups, resp. The four compounds show electrocatalytic activity in proton reduction in DMF solutions in presence of acetic acid; their activity is compared using cyclic voltammetry and quantified with gas chromatog.
Different reactions of this compound(Nickel(II) chloride ethylene glycol dimethyl ether complex)Application of 29046-78-4 require different conditions, so the reaction conditions are very important.
