Preparation of CuO nanoparticles by thermal decomposition of double-helical dinuclear copper(II) Schiff-base complexes
In this paper, two double helical dinuclear copper(II) complexes of bis-N,O-bidentate Schiff base ligands bis(3-methoxy-N-salicylidene-4,4'-diaminodiphenyl)sulfone (L1) and bis(5-bromo-N-salicylidene-4,4'-diaminodiphenyl)sulfone (L2) were prepared and characterized by elemental analyses (CHN), as well as thermal analysis. Elemental analyses (CHN) suggested that the reaction between ligands and ...
متن کاملSynthesis, Spectroscopy and Magnetism of Alkoxobridged Dinuclear Copper(II) Complexes with 2 Amino Picolines as the Ligands
The synthesis, spectroscopic and magnetic characterization of a series of new alkoxo-bridged binuclear copper (II) compounds are described. All complexes have the general formula [Cu (m-OR)(L)2]2(ClO4)2 · x H2O, in which m-OR = CH3O-, C2H5O- or C3H7O-<e...
متن کاملDitopic bis-terdentate cyclometallating ligands and their highly luminescent dinuclear iridium(III) complexes.
A new family of bridged cyclometallating ligands is reported, which incorporate two terdentate N(∧)C(∧)N-coordinating binding sites linked via pyrazine, pyrimidine or pyridazine units. Dinuclear Ir(III) complexes of one ligand have been prepared and crystallographically characterised; they display intense red phosphorescence.
متن کاملCationic dinuclear platinum and palladium complexes with bridging hydrogermylene and hydrido ligands.
Hydride-abstraction reactions of hydrido(dihydrogermyl) complexes [MH(GeH2Trip)(dcpe)] [M = Pt, Pd, Trip = 9-triptycyl, dcpe = 1,2-bis(dicyclohexylphosphino)ethane] with B(C6F5)3 led to the unexpected formation of new cationic (μ-germyl)(μ-hydrido) dinuclear platinum and palladium complexes, [{M(dcpe)}2(μ-GeHTrip)(μ-H)](+).
متن کاملStrong luminescent copperIJI) halide coordination polymers and dinuclear complexes with thioacetamide and N,N′-donor ligands†
Direct reactions between copperIJI) halides, thioacetamide (TAA) and 4,4′-bipyridine (4,4′-bpy) or pyrazine (pyz) in MeCN led to the formation of mixed ligand compounds [Cu2Cl2IJTAA)2IJ4,4′-bpy)]n (1), [Cu2X2IJTAA)4IJ4,4′-bpy)]·(4,4′-bpy) (X = Cl (2), Br (3) and I (4)) and [Cu2Cl2IJTAA)2IJpyz)]n (5), and the binuclear complex [Cu2I2IJTAA)4] (6). The formation of these compounds strongly depends...
