Synthesis, Spectroscopy and Magnetic Characterization of Five Dinuclear Copper(II) Complexes with 2, 3 or 4-Pyridinemethanol as the Ligand
The synthesis, spectroscopy and magnetic characterization of five new dinuclear copper(II) complexes are described. All five compounds have the general formula [Cu2(L)4(O-R)2](Cl)2 or [Cu2(L)2(Cl)2](Cl)2, in which R = CH3 or H, L=2, 3 or 4-pyridinemethanol as L2, L3 or L4, respectively. The title compounds consist of dinuclear units with bridging methoxo groups in [Cu2(L4)4(O-CH3)2](Cl)2, hydro...
متن کاملSynthesis of Binuclear Copper (II) Complexes with Expanded Porphyrins
The synthesis and characterization of some new binuclear copper (II) complexes, based on the use of large, pyrole-containing macrocycles, the so called "expanded porphyrins", [Cu2(macrocycle)]+4 is described. Electron Spin Resonance (ESR) studies indicate a weak "half-field line", which is characteristic of the Cu(II)-Cu(II) dimer, is observed at about 1600G. The obser...
متن کاملThe influence of amino acid side chains on water binding to the copper(II) in bis(N,N-dimethyl-L-alpha-isoleucinato)-copper(II): an EPR and molecular mechanics study.
Simulations were done of the electron paramagnetic resonance (EPR) spectra for bis(N,N-dimethyl-L-alpha-isoleucinato)copper(II) dissolved in deuterated methanol as a function of temperature. They indicated different behaviour of the complex below and above 300 degrees K. The effect was examined by the conformational analysis of the copper(II) complex with a new molecular mechanics force field.
متن کاملThe study of electron-orbital properties of bipolar energy of complex (2,6-diaminopyridinium bis (4-hydroxy-pyridine-2,6,6-dicarboxylate) dihydrate chromate III))) with alteration of ligands by computational methods
In this report, using the ab initio method of stability and electron-orbital properties of the complex (2,66-diaminopyridinium bis (4-hydroxy-pyridine-2, 6-dicarboxylate) dihydrate chromate III) with a change of ligand at position 17 It has been studied with ligands such as F, Cl, Br,,, and. The results indicate changes in energy levels, bipolar moments, and sustainability rates due to these ch...
