2,4-Diamino-6-phenyl-1,3,5-triazin-1-ium nitrate

Hydrogen bonds are ordered into a repeated sequence of homo- and hetero-synthons, R 2 2 (8)R 3 3 (10)R 2 2 (8)R 2 2 (8)R 2 4 (8)R 3 3 (10) as ring motifs. The paired cations form R 2 2 (8) ring motifs through base pairing of NHN hydrogen bonds. All other patterns include both cations and anions.

Crystal Structure Determination and Hydrogen-Bonding The crystal structure of picolinamide displays an ex- tended hydrogen-bond network generated by amide-am- ide synthons. Each picolinamide molecule is involved in two intermolecular N--O···H hydrogen bonds (Figure 3). Figure 3. A portion of the crystal packing viewed in the ba plane. Intermolecular hydrogen bonds, N--H···O with sym-

Crystal Structure and Hydrogen Storage Properties of novel

Novel Mg-Zr-A (A=Na, Li and K) hydrides have been synthesized by the gigapascal hydrogen pressure method. Their crystal structures were analyzed based on synchrotron X-ray diffraction (XRD) patterns. In the Mg-Zr-H system, the Mg-Zr hydride with FCC structure was formed under 8 GPa and 873 K. Crystal Structure and Intramolecular Hydrogen Bonding X-ray diffraction study. The crystal structure of the molecule has a planar geometry with intramolecular hydrogen bonding. The hydrogen bonding is also evaluated in a solution state by spectroscopic techniques. In nature, intramolecular hydrogen bonding plays an important role in holding the secondary structure of Crystal structure and hydrogen absorption-desorption Aug 15, 2017 · The hydrogen storage alloys are classified into groups in terms of their crystal structure and composition. So far, AB 5-type rare earth-based hydrogen storage alloys or AB 3-type superlattice alloys have been used as the negative electrode active material for commercial Ni-MH batteries , , . These alloys show good initial activation, high hydrogen diffusibility, high absorption/desorption

Crystal structure, hydrogen bonding, mechanical properties

May 16, 2019 · The crystal structure, hydrogen bonding, mechanical properties and Raman spectrum of the lead uranyl silicate monohydrate mineral kasolite, Pb(UO 2)(SiO 4)·H 2 O, are investigated by means of first-principles solid-state methods based on density functional theory using plane waves and pseudopotentials.

McCusker Institut j~r KristaUographie und Petrographie, ETH, CH-8092 Ziirich, Switzerland (Received 28 April 1983, revised 7June 1983) To determine whether or not there is a structural basis for the unusually low n-butane sorption capacity observed for the hydrogen form of zeolite rho (H12AI12Si380ss), and New Zr3MNx (M = Co, Ni) Subnitrides:Theoretical Analyses Dec 03, 2020 · The crystal structures of the input alloys and hydrides based on them were determined by analyzing the arrays of diffractograms obtained in a DRON-3.0M powder diffractometer (in the CuK -radiation) with the help of the WINCSD software package [].The hydrogen-sorption properties of alloys were studied with the help of a Sieverts-type device.


The crystal-structure refinement indicates that all H 2O groups are fully occupied, even those that are only hydrogen-bonded within the structure. The full site-occupancy likely re ects the fact that the H 2O groups are critical to the cross-linkage of the SrCa borate layers, thus contrib-uting to the structural stability of the mineral. Synthesis of 2,6-diaminopyridine substituted -oxoketene S Oct 19, 2013 · The crystal structure confirms the enamino structure and shows extensive use of C-HX (X = N, O, and S) weak hydrogen bonding interactions, Synthesis, Crystal Structures, and Hydrogen-Storage Complex Eu(AlH4)2 and Sr(AlH4)2 hydrides have been prepared by a mechanochemical metathesis reaction from NaAlH4 and europium or strontium chlorides. The crystal structures were solved from powder X-ray diffraction data in combination with solid-state 27Al NMR spectroscopy. The thermolysis pathway was analyzed in detail, allowing identification of new intermediate EuAlH5/SrAlH5 compounds

Crystal structure and hydrogen bonding system in cellulose

The crystal and molecular structure, together with the hydrogen-bonding system in cellulose I(alpha), has been determined using atomic-resolution synchrotron and neutron diffraction data recorded from oriented fibrous samples prepared by aligning cellulose microcrystals from the cell wall of the freshwater alga Glaucocystis nostochinearum.
