(b) Cases in which a stable metal-ligand system undergoes a change in the oxidation state of the metal atom on interaction with another reagent. This is followed by an interaction between the metal atom and its ligand. As a result of this process the metal ion may be recovered either in...
The possibility of changing the reactivity of organometallic and coordination compounds by changing the magnetic state due to oxidation of the redox-active phenolic group in the ligand is demonstrated. It is proposed to use ligand oxidation as a method for intramolecular activation of metal complexes....
A 13C NMR Study on Collagens in the Solid State: Hydration/ Dehydration-Induced Conformational Change of Collagen and Detection of Internal Motions We recorded 13C NMR spectra of type I and IV collagens in the anhydrous and hydrated states, in order to confirm our previous assignment of peaks...
Infrared spectroscopy of a 15N-substituted macrocycle indicates these lower frequency bands involve imine vibrations. Formation of the nickel(I) or copper(I) carbonyl adducts results in return of the usual infrared imine bands. The oxidation state of the metal complexes is discussed in reference to...
Compounds with the ligands OSF5, OSeF5, and OTeF5 are now known for most of the chemical elements. The ability of these ligands to stabilize the highest valency levels of the central atoms to which they are bound is unsurpassed by any other polyatomic ligand. Examples are Xe(OTeF5)...
In the solid state, anions [M(VI)O(O(2))(2)(OR)](-) are typically pentagonal pyramidal (oxo in apical site) while [M(VI)O(3)(OR)](-) are tetrahedral. The data indicate that an equatorial ligand position is the site of alkoxo oxidation in [M(VI)O(O(2))(2)(OR)](-) ...
;CONSTITUTION: Both surfaces of a solid-state electrolyte having specific properties are coated with electrode materials and while a voltage is impressed between the electrodes or the electrodes are shorted from each other, oxygen is supplied to one side of the solid-state electrolyte and the ...
Density functional theory calculations show that this increase in the formal iridium oxidation state drives the formation of holes on the oxygen ligands in direct proximity to lattice vacancies. We argue that their electrophilic character renders these oxygen ligands susceptible to nucleophilic acid–base...
Our findings suggest that the effects of E2 on NMDAR-dependent synaptic physiology in the hippocampus likely result from recruitment of NR2B-containing NMDARs to synapses rather than from increased expression of NMDARs or changes in their phosphorylation state....
Catalysts adapted to catalyse the oxidation of carbon monoxide to carbon dioxide comprise palladium, one or more of the metals platinum, ruthenium, rhodium and iridium and one or more of the metals copper, nickel, cobalt, iron, manganese, silver, lanthanum, cerium, praseodymium and neodymium on ...
