Simultaneous Occurrence of Quadruple Lewis Acid-Base Interactions between Selenium Atoms in Selenocarbonyl Dimers
(Wiley VCH Verlag, 2017-12)
High-level quantum chemical calculations are performed to investigate C=Se⋅⋅⋅Se=C interactions. Bounded structures are found with binding energies between −4 and −7 kJ mol−1. An energy decomposition analysis shows that ...
Simultaneous occurrence of quadruple lewis acid–base interactions between selenium atoms in selenocarbonyl dimers
(Wiley VCH Verlag, 2017)
High-level quantum chemical calculations are performed to investigate
C=Se···Se=C interactions. Bounded structures are
found with binding energies between @4 and @7 kJmol@1. An
energy decomposition analysis shows that ...
Thermal behaviour of polymetallic metal carbonyls with Fe-Fe, Fe-Hg and Hg-Hg bonds containing Lewis bases.
(Soc Brasileira Quimica, 1996-07-01)
The thermal behaviour of polymetallic metal carbonyls containing Fe-Fe, Fe-Hg and Hg-Hg bonds and Lewis bases, such as [Fe-3(CO)(8)(L)(2)] (L = 1,10-phenantroline,2,2'-bipyridine), [Fe(CO)(4)(HgCl)(2)] and [Fe(CO)(4)(HgC ...
Lewis Acidity/Basicity Changes in Imidazolium Based Ionic Liquids Brought About by Impurities
(American Chemical Society, 2015)
We herein report on the effect that water molecules, present as impurities, in the vicinity of an ionic liquid model structure, may induce on the Lewis acidity/basicity patterns normally observed in these materials. Depending ...
Reaction mechanism of hydrogen activation by frustrated Lewis pairs
(KeAi Publishing Communications Ltd., 2019)
Typically, a Lewis acid and a Lewis base can react with each other and form a classical Lewis adduct. The neutralization reaction can however be prevented by ligating the acid and base with bulky substituents and the ...
''Jabberwocky, by Lewis Carroll: Analysis of Linguistics Variations Based on Translation Studies
(Univ Estadual Paulista, Fundacao Editora Unesp, 2019-07-01)
This paper is an analysis based on the functional approach of the descriptive translation studies using the model of Jose Lambert and Van Gorp (1985) on the linguistic variations present in the poem Jabberwocky written by ...
