Hydrogen bondsInvestigation of a series of crystal structures of ammonium and phosphonium cyclopentadienide complexes suggests that the free Cp anion cannot be considered as a “naked” anion. Analyses of short cation–anion interactions show that networks of C−H⋅⋅⋅Cp − bonding...

How do hydrogen bonds in water form? Which of these compounds exhibit hydrogen bonding? a) CH4 b) NO c) NH3 d) CH3-O-CH3 What is hydrogen bonding? Under what conditions can hydrogen bonds be formed? Which of the following compounds exhibits hydrogen bonding: H2, H3, OH, CH3I, C6H5,...
Nevertheless, even the isotropic 1H shielding can provide valuable information: it has been long established that siso decreases on the formation of hydrogen bonds (HBs)4–6. A quantitative investigation between the other components of the shielding tensor and the HB geometry in liquid water7,8 ...

In the crystal structure of potassium hydrogen dichloromaleate there are two short hydrogen bonds of 2.44 A. The 'heavy-atom' structure is centrosymmetric (space group P1) with centers of symmetry in the middle of the O-O bonds, suggesting centered hydrogen bonds. However, earlier unconventional...
We find the system's ability to form interparticle hydrogen bonds when sheared into contact elicits SJ. We demonstrate this with charge-stabilized polymer microspheres and non-spherical cornstarch particles, controlling hydrogen bond formation with solvents. The propensity for SJ is quantified by ...
