A new calculating method for metal-metal bonding energy in bi-bridge and bi-Mo (v) clusters has been proposed by virtue of its suitability to the elect- ro... J Li,W Chen - 《Journal of Fuzhou University》 被引量: 1发表: 1985年 Effect of Thermal Stress on Crack Initiation in AlN-...
The spectra show a large amount of interaction between the metal d[pi] orbitals and the acetylide [pi] orbitals. Evidence for this is obtained from the splitting of metal-based ionization bands, from the shifts in Cp-based and acetylide-based ionizations, from the changes in ionization cross...
Polyoxometalates (POMs) are discrete molecular structures composed of metal cations bridged by oxide anions. They are not multi-metal species with metal–metal bonding, one conventional definition of “clusters,” but they are clusters in the generic sense of the word. A number of general reviews...
N Takagi,A Krapp,G Frenking 摘要: The bonding situation of homonuclear and heteronuclear metal-metal multiple bonds in R(3)M-M'R(3) (M, M' = Cr, Mo, W; R = Cl, NMe(2)) is investigated by density functional theory (DFT) calculations, with the help of energy decomposition analysis...
The short Tl−Ni distance in Tl2Ni(CN)4 is the first example of metal−metal bonding between these two metals. The strength of the metal−metal bonds in this series of compounds was assessed by means of vibrational spectroscopy. Rigorous calculations, performed on the molecules in D4h ...
The nature of M–M bonding and aromaticity of [M2(NHCHNH)3]2(μ-E)2 (E = O, S; M = Nb, Mo, Tc, Ru, Rh) was investigated using atoms in molecules (AIM) theory, electron localization function (ELF), natural bond orbital (NBO) and molecular orbital analysis. These analy...
Method and the apparatus for sticking the metal file to the leading edge of airfoil provides the metal fairing uniformly and rapidly to the leading edge. A metal fairing attaching device(1) comprises as follows. A hard yoke(2) which is inserted so that the conduction heater means(30) heat ...
An analytical LCAO MO perturbation model has been developed to treat the M-X2 (and M-YZ) interactions where X2 (YZ) is a closed-shell diatomic molecule and M a transition-metal atom. In a linear fragment M-X-X (M-Y-Z), the metal orbitals have larger off-diagonal matrix elements |...
The methylene protons in the ligand are shifted downfield in the (1)H NMR spectra, and the diamagnetic anisotropy of the metal-metal bond was calculated as -3500 × 10(-36), -3900 × 10(-36), and -5800 × 10(-36) m(3) molecule(-1) for 2(red), 3, and 4(ox) respectively. ...
