Arsenic pentafluoride, crystal structureReinvestigation of an earlier reported preliminary X-ray structure verifies the coordination of AsF5 to the oxygen atom of CF3SNSO. The resulting differences in bond lengths of the cumulene system SNSO via an attachment of the Lewis acid are mentioned....

The novel boron compounds have been characterized by multinuclear NMR, IR and mass spectra. The structure of VII has been determined by single-crystal X-ray diffraction.Access through your organization Check access to the full text by signing in through your organization. Access through your ...
2023, Journal of Molecular Structure Citation Excerpt : Moving electrons from filled Lewis's orbitals to empty non-Lewis's orbitals can make donor-acceptor interactions more sTable. When you look at the electron concentrations of the single and double bonds, you can see that the molecules in the...
1.Systematic calculations of the electronic structure of the fluorocarbon compounds CF, CF2, CF3, C2F, and C2F2 within the framework of the same nonempirical Xa method of discrete variation permitted elucidating the correlation between the electronic characteristics of these molecules and the features...
(-)2, [CBr(3)](+)[Al(OR(F))(4)](-)3, [CBr(3)](+)[(R(F)O)(3)Al-F-Al(OR(F))(3)](-)4 (R(F) = C(CF(3))(3)) were prepared in 56 to 85% yield from CX(4) (X = Cl, Br) and the corresponding silver salts (weight balance, NMR, IR, X-ray structure ...
Correlation of the calculated SIMes affinity with the carbene carbon chemical shift in the 13 C NMR spectrum reveals that trans Au(CF 3 )F 2 (SIMes)] and [Au(CF 3 ) 3 (SIMes)] nicely follow the trend in Lewis acidities of related organo gold(III) complexes. Furthermore, a new ...
This ratio was be-lieved to be limited by the oxidative stability of the transi- tion-metal fragment, which functionsin these complexes as a Lewis base. We thank the CNPq (Brazil) for a grant to TMG C. The addition of two Ag⊕ ions to a basic metal center has been achieved by ...
