Question: Draw a Lewis structure that obeys the octet rule for each of the following ions. Assign formal charges to each atom. {eq} 1.\ ClO_3^-\\ 2.\ ClO_4^-\\ 3.\ NO_3^-\\ 4.\ NH_4^+ {/eq}...
A missing X-ray structure of Ph3AsB(C6F5)3 is described. Analyses of molecular structures, orbitals, dissociation energies and electron density distributions reveal crucial influence of non-covalent interactions on the Ph3EB(C6F5)3 stability.
The crystal structure of 2,6-lutidine (2,6-dimethylpyridine, C7H9N), has been determined at 120 (2) K following in situ... Andrew,D.,Bond,... - 《Acta Crystallographica》 被引量: 1发表: 2001年 Synthesis and crystal structures of β-[Be(DMF)4]I2, [Be(Pyr)4]I2...
To understand why boron trifluoride (BF₃) is a weaker Lewis acid compared to boron tribromide (BBr₃) and boron trichloride (BCl₃), we need to analyze the concept of back bonding and the electronic structure of the involved elements. 1. Definition of Lewis Acids: Lewis acids are ...
The GaI3 complex is believed to be analogous on the basis of analytical and spectroscopic data. InBr3 affords a 1 :1 complex with an ionic structure [(Ph2PCH=CHPPh2)2lnBr2]+ [InBr4]- in which the cation contains the original cis-ligand. With Inl3 also a 1:1 adduct is obtained, ...
The Lewis acid-base concept is fundamental for the understanding and the prediction of chemical structure and reactivity. For instance, boranes (BR3) and phosphines (PR'3) represent prototypical Lewis acids and bases, respectively, and as such, they are prone to form stable donor-acceptor ...
Routes to stannoles, stannolenes, and 1-stanna-4-bora-2,5-cyclohexadienes - crystal structure of a triorganotin cation stabilized by p-coordination. Di-1-alkynyltin compounds ( 1 ) react with triorganoboranes R3B [ 2a (REt), 2b (R i Pr)] to give (21-alkynyl)tin compounds 3 (...
In several cases, zwitterionic intermediates could be detected by multinuclear magnetic resonance spectroscopy (1H, 11B, 13C, and 119Sn NMR), and the molecular structure of such an intermediate as well as that of the final product, an 1,4-stannabora-cyclohexa-2,5-diene, could be determined...
