Crystal Structure and Magnetic Property of the Binuclear Manganese(III) Complex with /u-Acetate and Di-ji-Alkoxo Bridges
Multinuclear manganese sites that are involved in the catalysis of reactions vital to biological systems are being steadily recognized and studied. Besides the photosynthetic water-oxidizing complex, which is known to utilize 4 Mn ions for the oxidation of water to molecular oxygen [1], evidence has accumulated that the Mn site of the pseudo-catalase from Lactobacillus planatrum is comprised of...
متن کاملMagnetic Properties and Crystal Structure of a 3,5-Dimethylpyrazolate-Bridged Binuclear Copper(II) Complex
Z. Naturforsch. 56 b, 970-974 (2001); received November 27, 2000 Binuclear Copper(II) Complex, Super-Exchange Interactions, Antiferromagnetic Coupling [CuiL(prz)] (prz = 3,5-dimethylpyrazole and L = l,3-bis(5-bromo-2-hydroxybenzylidene)propan-2-ol) was synthesized and its crystal structure determined. It crystallizes in the or thorhombic space group Pbca with a = 14.160(9), b = 15.109(4), c = ...
متن کاملSynthesis of Binuclear Monohydroxo Bridged Copper(II) Complexes with 1,10-Phenanthroline and 4,4'-Dimethyl-2,2'-Bipyridine
Tow new compound of type [(chelate)2Cu-OH-Cu(chelate)2] X3.nH2O, where chelate=1,10-phenanthroline; X=Cl¯(n=3.5) and chelate=4,4'-dimethyl-2,2'-bipyridine; (n=5) have been synthesized and their properties investigated.

متن کاملBinuclear Nickel(II) Complex Containing 6-Methyl-2,2'-bipyridine and Chloride Ligands: Synthesis, Characterization, Thermal Analyses, and Crystal Structure Determination
A new binuclear complex of [{NiCl(6-mbipy)}2(μ-Cl)2] (1) was prepared from the reaction of NiCl2.6H2O and 6-methyl-2,2'-bipyridine (6-mbipy) in a mixture of methanol and acetonitrile. Suitable crystals of 1 for X-ray diffraction measurement were obtained by slow evaporation of the resulted green solution at room ...
متن کاملStructures and anti-cancer properties of two binuclear copper complexes.
The crystals of two binuclear copper-based complexes were obtained. One complex can remarkably induce apoptosis and inhibit angiogenesis to mediate tumour growth at a greater extent. Furthermore, this complex showed a strong energy-dependent and non-endocytotic uptake and exhibited multiple anti-cancer functions by inhibiting the expressions of p-Akt and p-Erk1/2 proteins and by decreasing the ...
