The structures and bonding of a series of five-membered rings with BN bonds CxNyBzH5 (x + y + z = 5) and their most stable deprotonated anions CxNyBzH4 as well as anionic rings CxNyBzH5 have been investigated at the MP2/6311++G(d,p) level of theory. The great majority of these ...
The binding energies and electronic properties of substituted fullerenes ${\mathrm{C}}_{58}$${\mathrm{B}}_{2}$ and ${\mathrm{C}}_{58}$${\mathrm{N}}_{2}$ have been calculated by a self-consistent-field molecular-orbital (MO) method; their structures are optimized by a MO method ...

A systematic density functional study was performed on the structures and bonding features in a homologous metal–metal (M–M) host–guest series M<sub>2</sub>@C<sub>50</sub>X<sub>10</sub> (M = Zn, Cd, Hg; X = CH, N, B). Calculations indicated that D<sub>5d</sub> conformer...
The crystal structures of the title complexes [(HgCl<sub>2</sub>)<sub>2</sub>L](1) and [HgL(OH<sub>2</sub>)][ClO<sub>4</sub>]<sub>2</sub>(2) have been determined by X-ray diffraction. Complex (1) crystallises in the monoclinic space group P2<sub>1</sub>/n, Z= 2, ...
10, the abundance of boron has been pointed out as a possible reason for MgB2’s superconductivity, considering both covalent B-B and ionic B-Mg bonding. It is important to note that these bonds are sufficiently strong, leading to a strong electron-phonon coupling. To the best of the ...
After the composition adjustment, the wetting angle of the Co-Ni-Fe-Cr- (14-20) Ti alloy on the Si_3N_4 reached 20.0°, and the strong bonding between the Si_3N_4 and the brazing filler was obtained. 展开 关键词: Si_3N_4 wetting high-temperature brazing filler interfacial reaction ...

The structure, bonding and energetics of B2AlHnm (n = 3−6, m = −2 to +1) are compared with corresponding homocyclic boron, aluminum analogues and BAl2Hnm using density functional theory (DFT). Divalent to hexacoordinated boron and aluminum atoms are found in these species. The geomet...
