Synopsis: The partial order among Bravais types of lattices obtained by considering special cases is derived from their space-group symmetry and applied to continuous equi-translation phase transitions.
Synopsis: The mimetic twinning of aragonite is explained by the high degree of pseudo-symmetry of the crystallographic orbits and the action of the twin operation on the structure slices which form the composition surface.
Synopsis: SHELXT automates routine small-molecule structure determination starting from single-crystal reflection data, the Laue group and a reasonable guess as to which elements might be present.
Synopsis: A simple approach to estimate temperature-dependent isotropic motion of hydrogen atoms is proposed. The model is validated against experimental data.
Synopsis: The article describes decorated generalized Penrose tiling as a potential quasilattice for models of decagonal quasicrystals. Its advantage over the conventional Penrose tiling is that its long-range order can be continuously changed if the tile decoration is fixed.
Synopsis: Cartesian real spherical harmonics for l 20 and the corresponding normalization factors for the deformation density functions with an accuracy to 35 significant figures have been generated using the Wolfram Mathematica software and converted to a Fortran90 code.
Synopsis: The affine and Euclidean normalizers of the subperiodic groups are derived and listed.
Synopsis: In order to characterize molecular-replacement search spaces, the structure of Sohncke groups is examined. It is observed that proteins most often crystallize in Sohncke groups with small torsion subgroups.
