Hint: Consider how the hydrogen bond forms between the two molecules and how this interaction stabilizes the dimer. Step 5: ConclusionThus, benzoic acid is an example of a compound that forms a dimer due to hydrogen bonding. The dimerization is a result of the strong intermolecular hydrogen bon...
Hydrogen bondingIntermolecular interactionThe molecular and crystal structures of 4-ethynylcyanobenzene are reported. The packing of molecules in the crystal is found to be homologous with the crystal structures of HCN, cyanoacetylene and 4-cyano-4′-ethynylbiphenyl. Alternatively, these four crystals ...
All intermolecular distances are indicative of normal nonbonded contacts except in a direction parallel to the crystallographic a axis where hydrogen bonding is indicated. 展开 DOI: 10.1021/ic50067a017 被引量: 39 年份: 1968 收藏 引用 批量引用 报错 分享 ...
The reaction of PCl3 with CyNH2 in a 1:3 ratio affordedthe dichloro-λ3-cyclodiphosphazane, cis-[ClP(μ-NCy)]2 (2), whereas the corresponding 1:5 reaction gave the bis(amido)-λ3-cyclodiphosphazane cis-[Cy(H)NP(μ-NCy)]2 (3) in quantitative yield. The dichloro derivative 2 w...
The second carboxyl oxygen is involved in the intermolecular hydrogen bonding to the carboxyl group of another peri-naphthalene. In the two unique carboxy groups the carbon-oxygen bond which is intramolecularly hydrogen bonded is shorter (1.253(3) and 1.244(3) Å) than the bond involved in ...
We show that the microscopic nonlinearity of the DHNPH molecules is particularly sensitive to variations in phenolic OH characteristics such as the orientation and intermolecular interactions. 展开 关键词: Hydrogen bonding Crystal structure Second harmonic generation Intermolecular forces Powders ...
In the lattice, the hydrogen-bonded sites form infinite chains interconnected via a three-dimensional network of intermolecular van der Waals contacts and π-π interactions. Therefore, the spin transition of 1 involves the synergetic influence of electrostatic and elastic interactions, which cause the...
hydrogen bondingThe conformations of diethyl 2-hydroxypropylphosphonate in CDCl 3 were studied by means of NMR spectroscopy. This compound forms species in which intermolecular hydrogen bonding prevails in concentrated solutions whereas intramolecular bonds are predominant in dilute solutions. Usually both ...
