Redox non-innocent ligands have recently emerged as interesting tools to obtain new reactivity with a wide variety of metals. However, gold has almost been neglected in this respect. Here, we report mechanistic investigations related to a rare example of ligand-based redox chemistry in the coordination sphere of gold. The dinuclear metal-centered mixed-valent AuI -AuIII complex 1, supported by ...

The title mixed-ligand copper(I) complex, [Cu(C(18)H(13)N(4)O(5)S)(C(18)H(15)P)(2)], was synthesized via solvothermal reaction of [Cu(PPh(3))(2)(MeCN)(2)]ClO(4) and sulfasalazine [systematic name: 2-hydr-oxy-5-(2-{4-[(2-pyridylamino)sulfon-yl]phen-yl}diazen-yl)benzoic acid]. The mononuclear complex displays a trigonal coordination geometry for the Cu(I) atom, which is surrounded by two P-atom d...
A series of cobalt(ii) complexes of a highly electron-withdrawing amido ligand, [N(C6F5)(C6H3Pr(i)2-2,6)](-) (L), were synthesized and structurally characterized. Mononuclear [CoL(Cl)(TMEDA)] (3) and heterobimetallic [CoL2(μ-Cl)Li(THF)3] (4) were obtained by direct metathetical reactions of anhydrous CoCl2 with one molar equivalent of [LiL(TMEDA)] (1) (TMEDA = Me2NCH2CH2NMe2) and [LiL(THF)3] (2...
Mixed-ligand ruthenium(II) complex with 2,2′-bipyridine and 1,10-phenanthroline-3,8-dicarboxylic acid the composition [Ru(phen-C)(bpy)2]Cl2·5H2O (bpy = 2,2′-bipyridine, phen-C 1,10-phenantroline-3,8-dicarboxylic acid) has been synthesized characterized by spectral data. The tested as photocatalyst in aerobic oxidation reactions, including transformation of arylboronic acids to phenols, primary ...
A description for the ligand function of tetrathiocyanatozincate selective electrode, has been proposed, using a multi-species approach model. This model takes into account simultaneous phase-boundary, diffusion-controlled, processes ion exchange between tetrathiocyanatozincate, thyocyanate and foreign ions unable to form zinc complexes, as well distribution neutral complex phases, partial deco...
Six new diiridium complexes containing 2‐methyl‐6‐phenylpyridyl as the cyclometalating ligand with a μ2‐oxamidato or μ2‐dithioxamidato bridge have been synthesized in 60‐73% yields. These were revealed by multinuclear NMR spectroscopy to contain inseparable mixtures of diastereomers (rac, DD/LL and meso, DL) bridges anti syn configurations. The remarkable variety isomers present was confirmed X...
An octahedral cobalt(III) complex, trans-[(Me2bpb)Co(bzlan)2]ClO4 (1), with H2Me2bpb = N,N’-(4,5-dimethyl-1,2-phenylene)dipicolinamide and bzlan = benzylamine, has been synthesized and characterized by elemental analyses, IR, UV-Vis, and 1H NMR spectroscopy. The structure of this complex has been determined by X-ray crystallography. The Me2bpb2– is a di-anionic tetradentate ligand furnishing a ...
