A sample of Ta2O5, ditantalum pentaoxide, heat-treated in a `toroid'-type high-pressure chamber at P = 8 GPa and T = 1470 K, was studied by X-ray powder diffraction and high-resolution transmission electron microscopy (HRTEM). Two high-pressure modifications of Ta2O... hiện toàn bộ
Applications of the Cambridge Structural Database to molecular inorganic chemistryInternational Union of Crystallography (IUCr) - Tập 58 Số 3 - Trang 398-406 - 2002
A. Guy Orpen
Applications of the data in the Cambridge Structural Database (CSD) to knowledge acquisition and fundamental research in molecular inorganic chemistry are reviewed. Various classes of application are identified, including the derivation of typical molecular dimensions and their variability and transferability, the derivation and testing of theories of molecular structure and bonding, the i...... hiện toàn bộ
Novel tools for visualizing and exploring intermolecular interactions in molecular crystalsInternational Union of Crystallography (IUCr) - Tập 60 Số 6 - Trang 627-668 - 2004
Joshua J. McKinnon, Mark A. Spackman, Anthony S. Mitchell
A new way of exploring packing modes and intermolecular interactions in molecular crystals is described, using Hirshfeld surfaces to partition crystal space. These molecular Hirshfeld surfaces, so named because they derive from Hirshfeld's stockholder partitioning, divide the crystal into regions where the electron distribution of a sum of spherical atoms for the molecule (the promolecule)...... hiện toàn bộ
