When copper loses one electron from its 4s orbital, it forms the copper(I) ion (Cu⁺) with a +1 charge and an electron configuration of [Ar]3d¹⁰. On the other hand, copper can also lose two electrons, one from the 4s orbital and one from the 3d orbital. This results in ...
We prepared these ligands to study their bulkiness effect on imposing a particular configuration around the metal ion, e.g., a five- coordinate configuration. It has been shown [lo, 1l] that ligands which are suitable for imposing a five-coordinate arrangement around the central metal io...
Electron spectroscopy for chemical analysis and other studies of the anomalous behavior of the copper ion selective electrode in acetonitrile 来自 Semantic Scholar 喜欢 0 阅读量: 27 作者:JF Coetzee,WK Istone,M Carvalho 摘要: In the ion-selective electrode for copper(II) ion, which has the ...
Description of electron–ion interactions by the projector-enhanced wave (PAW) method. The plane-wave cutoff energy was set to 400 eV. The convergence criteria of energy and force were set to 10–4 and 0.03 eV Å−1, respectively. A vacuum layer of 15 Å was adopted to avoid the ...
Molecular formulae on the basis of percentage of constituent elements were found to be Cu(OAc)2(am)2, where OAc represents acetate ion and am any amine used. Conductivity measurements in nitrobenzene and formamide indicate that the complexes are nonelectrolytes and thus it is suggested that ...
Single-atom catalysts (SACs) with adjustable and isolated active sites have been applied to electrochemical catalysis32,33,34, showing potential in expelling C-C coupling in CO2RR. Particularly, the unique 3dtransition-metal-four nitrogen (M-N4) configuration consisting of an isolated single metal ...
MBD−2and MBD−1(previously MBD5 and MBD6, respectively), while the hATP7B structure displayed presence of one MBD (see more below). Both the MBDs of the XtATP7B structures were positioned distal to the ion uptake region, with MBD−2bound to the interdomain junction between the A-...
Copper is a group IB transition element on the periodic table and exists in four oxidation states: Cu0 Cu1+ (cuprous ion), Cu1+ (cupric ion), and Cu3+. In a natural state, copper is likely to be found in a variety of solid salts and compounds, but it can be found in the eleme...
A new look at the stereochemistry and electronic properties of complexes of the copper(II) ion As a consequence of the non-spherical symmetry of the copper(II) ion, d 9 configuration, and of the influence of the Jahn-Teller, and pseudo Jahn-Teller e... BJ Hathaway,J Emsley,RD Ernst,....
