Crystal structure and Hirshfeld surface analysis of (nitrato-κ ,')(1,4,7,10-tetra-aza-cyclo-dodecane-κ )nickel(II) nitrate.

The crystal structure of the title compound, [Ni(CHN)(NO)]NO, at room temperature, has monoclinic (2/) symmetry. The structure displays inter-molecular hydrogen bonding. The nickel displays a distorted bipyramidal geometry with the symmetric bidentate bonded nitrate occupying an equatorial site.

Structural Integrities of Symmetric and Unsymmetric -Bis-pyridyl Ethylene Powders Exposed to Gamma Radiation: Packing and Electronic Considerations Assisted by Electron Diffraction.

Radiation detection (dosimetry) most commonly uses scintillating materials in a wide array of fields, ranging from energy to medicine. Scintillators must be able to not only fluoresce owing to the presence of a suitable chromophore but also withstand damage from radiation over prolonged periods of time. While it is inevitable that radiation will cause damage to the physical and chemical properties of materials, there is limited understanding of features within solid-state scintillators that afford increased structural integrity upon exposure to gamma (γ) radiation.

Confinement and Separation of Benzene from an Azeotropic Mixture Using a Chlorinated B←N Adduct.

Separations of azeotropic mixtures are typically carried out using energy-demanding processes (e.g., distillation).

Crystal structure of tricarbon-yl[η-6--(tri-phenyl-phosphino)cyclo-hepta-2,4-dien-1-one]iron(0) tetra-fluoro-borate.

The mol-ecular structure of tricarbon-yl[η-6--(tri-phenyl-phosphino)cyclo-hepta-2,4-dien-1-one]iron(0) tetra-fluoro-borate di-chloro-methane hemisolvate, [Fe(CHO)(CO)]BF·0.5CHCl, as determined by single-crystal X-ray diffraction is reported. The two independent tricarbon-yl[η-6--(tri-phenyl-phosphino)cyclo-hepta-2,4-dien-1-one] iron(0) cations and their corresponding anions form dimers, which constitute the asymmetric unit of the structure parallel to the (100) plane.
