Crystal chemistry of HgBa2CaCu208+ and HgBa2Ca2Cu308+ Single-crystal X-ray diffraction results
Crystal structures of HgBa2CaCu206 + ~ (Hg1212 ) and HgBa2Ca2Cu308 + a (Hg1223 ) have been determined on single crystals at room temperature conditions by X-ray diffraction techniques. Both tetragonal specimens are isomorphous with compounds in the T1-Ba-Ca-Cu-O system. We observe excess oxygen in both samples on two sites near the z=0 plane: at (1⁄200) and close to (1⁄2, 0.4, 0) but no oxygen ...
متن کاملStructures of Furanosides: Density Functional Calculations and High-Resolution X-ray and Neutron Diffraction Crystal Structures
Highly accurate and precise crystal structures of methyl R-D-arabinofuranoside, methyl â-D-ribofuranoside, methyl R-D-lyxofuranoside, and methyl R-D-xylofuranoside have been determined at 100 K by X-ray crystallography. The structures of methyl R-D-arabinofuranoside and methyl â-D-ribofuranoside have also been determined at 15 K by neutron diffraction. Equilibrium (re) geometries of the same co...
متن کاملCrystal-chemistry of magnesiocarpholite: controversial X-ray diffraction, Mössbauer, FTIR and Raman results
Magnesiocarpholite, MgAl2Si2O6(OH)4, is a high-pressure/low-temperature mineral occurring in the metamorphic rocks of southern Tuscany (Monte Leoni and Monte Argentario). Chemical, Mössbauer, FTIR and single-crystal XRD characterizations were carried out to understand the symmetry and crystal chemistry of the mineral, since forbidden diffractions violating the space group Ccca have been reporte...
متن کاملOxides: neutron and synchrotron X-ray diffraction studies
We shall review some results from several areas of oxide science in which neutron scattering and X-ray synchrotron scattering exercise a complementary role to high-resolution transmission electron microscopy. The very highresolution time-of-flight neutron diffraction technique and its role in studies of the magnetic structure of oxides will especially be reviewed. The selected topics of structu...
متن کاملX-Ray and Neutron Diffraction with Amorphous Ti
The amorphous alloys Ti 6 7 Si 3 3 , V 6 7Si 3 3 , and Cr , 7 Si 3 3 were produced by sputtering. Their structure was investigated by X-ray and neutron diffraction. X-ray diffraction showed that the structure of the three metallic glasses is not isomorphous. Neutron diffraction showed that S i -S i atomic pairs occur preferentially with distances distinctly larger than the atomic diameter of th...
