In the title mol-ecule, C(15)H(17)N(3)O(2)S(2), the dihedral angle between the naphthalene ring system and the imidazole ring is 89.63 (2)°. The crystal structure is stablized by weak inter-molecuar C-H⋯π and N-H⋯π inter-actions.

In the mol-ecule of the title homoallylic amine, C(16)H(13)ClF(3)N, the dihedral angle between the two benzene rings is 84.63 (4)°. Weak intra-molecular N-H⋯F hydrogen bonds generate S(6) and S(5) ring motifs. In the crystal structure, weak inter-molecuar N-H⋯F hydrogen bonds link mol-ecules into centrosymmetric dimers which are arranged in mol-ecular sheets parallel to the ac plane.

Eleven simple neutral water-miscible compounds were tested for protective action against freezing damage to human red blood cells. All the compounds penetrated the cells at room temperature without damage, but only four, N-substituted amides, were active. These results are considered together with previously published work on freezing protection by other low molecuar weight solutes. The affinit...

In the title compound, [Ag(C(8)H(5)O(7)S)(C(10)H(8)N(2))](n), the Ag atom is tetra-coordinated by two 4,4'-bipydidine (4,4'-bipy) N atoms and two monodentate sulfonate O atoms of the 5-sulfoisophthalic acid (H(3)sip) ligands. Adjacent Ag atoms are bonded through four sulfonate O atoms, forming a dinuclear unit with an Ag⋯Ag separation of 3.384 (5) Å; they are further linked together by the 4,4'...

A new polymorph of dimesitylborinic acid (or hydroxy-dimesitylborane), C(18)H(23)BO, showcasing different crystal packing and symmetry, complements the previously reported polymorph [Weese, Bartlett, Murray, Olmstead & Power (1987 ▶). Inorg. Chem.26, 2409-2413; Entwistle, Batsanov & Marder (2007 ▶). Acta Cryst. E63, o2639-o2641]. The structure of the title compound contains only one mol-ecule i...

One of the most appropriate methods for elimination of trace impurities in helium is cryogenic adsorption process. So, in this study design and construction of cryogenic adsorption helium purification system (3 Nm3.hr-1, 80 bar) carried out using activated carbon as adsorbent at 77K. To evaluation of adsorption dynamics and effect of pressure on elimination of trace impurities, helium purificat...

The coupling behavior of time scales structural relaxation is investigated on the basis five different response functions for 1,2,6-hexanetriol, a hydrogen-bonded liquid with minor secondary contribution, and 2,6,10,15,19,23-hexamethyl-tetracosane (squalane), van der Waals bonded prominent process. Time are derived as inverse peak frequencies each function. For time-scale indices temperature-in...
