A document type is Article, introducing its new discovery.
Two binuclear complexes of cobalt(III) have been prepared with 3,3?,4,4?-tetrahydroxy-5,5?-di-tert-butylbenzaldazine (H4thBu) as bis(catecholate) ligand and two different ancillary ligands, 2,2?-bipyridine (bpy) or 2,2?-dipyridylamine (dpa). These compounds were characterized by 1H NMR spectra, electrochemical measurements and UV-Vis spectra. In one case, [Co2(dpa)4(thBu)]2+, electrochemical oxidation of the complexes occurs at the bridges as two closely spaced one-electron couples (E1/2 = 1 mV and 168 mV versus Fc/Fc+). Chemical oxidation of [Co2(dpa)4(thBu)]2+ using Ag+ is observed to occur as a stepwise two-electron process forming [Co2(dpa)4(thBuCat,SQ)]3+ or [Co2(dpa)4(thBuSQ,SQ)]4+ by UV-Vis spectrum. However, [Co2(bpy)4(thBu)]2+ shows no change in electronic spectrum under the same conditions of oxidation. This illustrates the dependence of redox properties of the binuclear Co(III) complexes on the nature of the nitrogen-donor ancillary ligands. In this report we discuss the effect of two different nitrogen-donor ancillary ligands on the0 oxidation behavior of binuclear Co(III) complexes.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.SDS of cas: 499-40-1. This is the end of this tutorial post, and I hope it has helped your research about 499-40-1
