Activation of [FeCl(dppe)Cp] (1) by chloride abstraction with Na[BArX4] (X = F, [B(3,5-(CF3)2-C6H3)4]; X Cl, [B(3,5-Cl2-C6H3)4]) permits reactions a range nitro aromatics, RC6H4NO2 (R halogen, Me, OMe, NO2 or NMe2), to give the cationic iron nitroso complexes [Fe{N(O)-C6H4R}(dppe)Cp][BArX4]) ([3][BArX4]). Similar 1 and [Fe(NCC6H4NO2)(dppe)Cp][BArX4] gave bimetallic [{Fe(dppe)Cp}2{?-N?CC6H4N(O)}...

Two bimetallic assemblies K[Cu(cyclam)][Fe(CN)6] 4H2O 1 and [Cu(L)][Cu(L )][Fe(CN)6] 6.5H2O 2 (cyclam = 1,4,8,11-tetraazacyclotetradecane; L = N,N -bis(2-pyridylmethylene)-1,3-propanediamine and L = N-2-pyridylmethylene-1,3-propanediamine) have been prepared from the reaction of [Fe(CN)6] 3 and the precursors [Cu(cyclam)] and [Cu(L)] , respectively, and their structure and magnetic properties s...

The response mechanism of the iron(III) chalcogenide glass membrane ion-selective electrode (ISE) in saline media has been studied using electrochemical impedance spectroscopy (EIS) and X-ray photoelectron spectroscopy (XPS). EIS equivalent circuits and XPS surface compositions for the FeIII ISE are consistent with the presence of two surface films probably comprising a outer surface layer (OSL...

Metal-catalyzed C–N cross-coupling generally forms C−N bonds by reductive elimination from metal complexes bearing covalent C- and N-ligands. We have identified a Cu-mediated that uses dative N-ligand in the bond-forming event, which, contrast to conventional methods, generates reactive cationic products. Mechanistic studies suggest process operates via transmetalation of an aryl organoboron Cu...

Four new NiII, CoII, ZnII, and CuII complexes with the promising anti-tuberculosis drug (E/Z)-N′-((5-Hydroxy-3,4-bis(hydroxymethyl)-6-methylpyridin-2-yl)methylene)-isonicotino-hydrazide (LH) were synthesized characterized by structural methods: single-crystal X-ray diffraction, vibrational spectroscopy, mass spectrometry. The ZnII metal ions form only amorphous phases various morphologies accor...
