Crystal structure of allyl­ammonium hydrogen succinate at 100 K

The asymmetric unit of the title compound, C2H8N(+)·C4H5O4 (-), consists of two allyl-ammonium cations and two hydrogen succinate anions (Z' = 2). One of the cations has a near-perfect syn-periplanar (cis) conformation with an N-C-C-C torsion angle of 0.4 (3)°, while the other is characterized by a gauche conformation and a torsion angle of 102.5 (3)°. Regarding the anions, three out of four ca...

High-Pressure Behavior of Hydrogen and Deuterium at Low Temperatures.

In situ high-pressure low-temperature high-quality Raman data for hydrogen and deuterium demonstrate the presence of a novel phase, phase II^{'}, unique to deuterium and distinct from the known phase II. Phase II^{'} of D_{2} is not observed in hydrogen, making it the only phase that does not exist in both isotopes and occupies a significant part of P-T space from ∼25 to 110 GPa and below 125 K...

Density functional study of hydrogen adsorption at low temperatures

In substitution of path integral isomorphism of the quantum particle, an effective polymer ring model is proposed in the density functional calculation for hydrogen adsorption in single-walled carbon nanotubes. The excess intrinsic Helmholtz energy for quantum particles includes contributions from hard-sphere repulsion, interatomic bonding and soft attraction. The first two contributions are co...
