Structure and Bonding 18: 177–216. Correlations with Acidity/Basicity and Energy of Interaction The strength of H-bonding increases with greater proton-donating ability of the A–H moiety and increasing proton-accepting power of the base B. Figure 5 shows the effect of differing basicity on ...
Lewis' classical picture of chemical bonds as shared-electron pairs evolved to the quantum-mechanical valence-bond and molecular-orbital theories, and the classification of molecules and solids in terms of their bonding type: covalent, ionic, van der Waals and metallic. Along with the more complex...
In terms of structure and bonding explain why water is a liquid and hydrogen sulfide is a gas at room temperature? The allene molecule has the following Lewis structure: Must all four hydrogen atoms lie in the same plane? If not, what is the spatial relationshi...
The compound NH_2CH_2CH_2CH_2NH_2(l) exhibits intermolecular hydrogen bonding and intramolecular hydrogen bonding. Use Lewis structure drawings to depict each type of hydrogen-bonding. Are the H-S bonds in hydrogen sulfide nonpolar covalent, polar covalent, or i...
We use charge balance and a secondary-coordination-sphere hydrogen-bonding interaction—evidenced by structure–activity relationship studies, computational modelling and crystallographic data—to stabilize L-type hydroxyl coordination to palladium, thereby facilitating the assembly of the key C–H cleavage ...
On the basis of our computations, we discuss the initially proposed layered structure of guanidine and identify both stabilizing and destabilizing cooperative interactions in the three crystalline dimensions. 展开 关键词: Hydrogen Guanidine Crystallization Crystallography, X-Ray Dimerization Hydrogen Bonding ...
NBO analysis is proved to be an efficient method to elucidate the most possible natural Lewis structure picture of orbitals. MCMH has been subjected to NBO analysis to elucidate the intra and intermolecular interactions between the filled and vacant orbital, which is a measure of hyperconjugation or...
Results of a density-functional study of linear HCN and CNH monomers, the corresponding hydrogen-bonded polymers, and a conjugated polymer (CHN)x with C and N atoms alternating along a zigzag chain are reported. Minimizing the total energy as a function of structure results in realistic structur...
However, fabricating 3D PCs structure by 3D printing colloidal particles is limited by control of assembly under a fast-printing speed. Here, we employ continuous digital light processing (DLP) 3D printing strategy with hydrogen bonds assisted colloidal inks for fabricating well-assembled 3D PCs ...
