We report the syntheses, electronic properties, andmolecular structures of a series of monoand dinuclear uranium(IV) hydrochalcogenido complexes supported by the sterically demanding but very flexible, single N-anchored tris(aryloxide) ligand (ArO)3N) 3 . The mononuclear complexes [((ArO)3N)U(DME)(EH)] (E 1⁄4 S, Se, Te) can be obtained from the reaction of the uranium(III) starting material [((...

The dinuclear arene ruthenium complexes [RuCl2{C6H5(CH2)3OCO-p-C6H4-OC8H17}]2 (1) and [RuCl2{p-C6H4(CH2COOCH CH3)2}]2 (2) have been obtained by dehydrogenation of the corresponding cyclohexadiene derivative with ruthenium chloride hydrat The single-crystal X-ray structure analysis of 2 shows the arene ligands to be involved in slipped-parallel p–p stacking interactions wit neighbouring molecule...

Mono- and dinuclear Cu(ii) complexes were prepared with pseudopeptidic open chain and macrocyclic ligands, respectively. They were characterized by UV-vis spectroscopy, EPR, HRMS and X-ray diffraction. The Cu(ii) cation is coordinated by two amines and two deprotonated amides, in a slightly distorted square planar coordination geometry. The complexes interact with several substituted dicarboxyl...

The dinuclear dichloro complexes [(g-arene)2Ru2(l-Cl)2Cl2] and [(g-C5Me5)2M2(l-Cl)2Cl2] react with 2-(pyridine-2-yl)thiazole (pyTz) to afford the cationic complexes [(g-arene)Ru(pyTz)Cl] (arene = C6H6 1, p-PrC6H4Me 2 or C6Me6 3) and [(g-C5Me5)M(pyTz)Cl] (M = Rh 4 or Ir 5), isolated as the chloride salts. The reaction of 2 and 3with SnCl2 leads to the dinuclear heterometallic trichlorostannyl de...

51V NMR Spectra, Oxovanadium, Nitrosylvanadium, Hydroxylamidovanadium The 51V NMR spectra are recorded for 3 dinuclear complexes {VO (ONR2 )2 O and 13 mononuclear vanadium (-f V) and (+III) chelate complexes of the general formula [VXYZ]Q, where X = 02-, NO"; Y = 02~, 022" , R2NO~; and Z = picolinate-(pic), dipicolinate2(dipic), nitrilo-tri(2-propanolate)3_, and o-phenanthroline (phen). Shieldi...

The effect of human serum on the minimum inhibitory/bactericidal concentrations of the potential antimicrobial agents ΔΔ-[{Ru(phen)2}2(μ-bb(n))](4+) {ΔΔ-Rubb(n); where phen = 1,10-phenanthroline, bb(n) = 1,n-bis[4(4'-methyl-2,2'-bipyridyl)]-alkane for n = 12 and 16} against four strains of bacteria--Gram positive Staphylococcus aureus and methicillin-resistant S. aureus (MRSA), and Gram negativ...

We have recently developed a series of arsenic ligands based on practical synthetic strategies. Herein, three kinds bidentate with rigid linkers were selected to construct dinuclear rhombic copper(I) iodide (CuI) complexes, whose structures analyzed by X-ray crystallography. They had sufficient solubility in organic solvents, and it was confirmed that their coordination forms kept the solutions...

The LCuBr-catalyzed C-H imidation of arenes by N-fluorobenzenesulfonimide (NFSI), previously reported by us, utilizes an inexpensive catalyst and is applicable to a broad scope of complex arenes. The computational and experimental study reported here shows that the mechanism of the reaction is comprised of two parts: (1) generation of the active dinuclear CuII-CuII catalyst; and (2) the catalyt...
