Effect of pressure on the crystal structure of alpha-glycylglycine to 4.7 GPa; application of Hirshfeld surfaces to analyse contacts on increasing pressure.
The crystal structure of alpha-glycylglycine (alpha-GLYGLY) has been determined at room temperature at pressures between 1.4 and 4.7 GPa. The structure can be considered to consist of layers. The arrangement of molecules within each layer resembles the antiparallel beta-sheet motif observed in proteins, except that in alpha-GLYGLY the motif is constructed through NH...O hydrogen bonds rather th...

The synthesis and X-ray diffraction analysis of a new acidic salt, [4-methyl-phenyl ammonium][(O-phenyl)(hydroxyl)phosphate], [4-CH3-C6H4NH3][(C6H5O)P(O)(O)(OH)], is reported. This compound crystallizes in the monoclinic system, with space group P21/c (a = 9.5147(4) Å, b = 23.2158(10) Å, c = 13.2740(6) Å and b = 111.244(4)°) with four independent components including two cations and two anions...
متن کاملDesign and simulation of a pressure sensor based on a two dimensional photonic crystal slab of PbMoO4
In this paper the design and three dimensions (3D) simulation of a photonic crystal (PC) pressure sensor is presented. The device is based on a 2D PC slab of PbMoO4. The simulations are based on finite element method (FEM) and finite-difference time-domain (FDTD) method and are done using CST STUDIO SUITE software. The sensitivity of the proposed sensor is calculated by considering the deformat...
متن کاملHigh-pressure single crystal X-ray diffraction study of the linear metal chain compound Co3(dpa)4Br2·CH2Cl2.
The crystal structure of the linear metal chain compound Co3(dpa)4Br2·CH2Cl2 (1) has been investigated up to a pressure of 13.6(2) GPa in a diamond anvil cell (DAC) using single crystal X-ray diffraction. The structure remains orthorhombic as the unit cell volume is reduced by 30% at 12.8 GPa. At 13.6(2) GPa the diffraction pattern is of very poor quality and not even reliable unit cell paramet...
متن کاملExploration of the high-pressure behaviour of polycyclic aromatic hydrocarbons: naphthalene, phenanthrene and pyrene.
The structural response of three members of the family of polycyclic aromatic hydrocarbons (PAHs) to high-pressure recrystallization from dichloromethane solutions is presented. Recrystallization of naphthalene in the 0.2-0.6 GPa pressure range does not result in the formation of a new polymorph. Furthermore, direct compression of a single crystal to 2.1 GPa does not result in a phase transitio...
