In this paper we classify the two-orbit polyhedra in classes 201 and 21 that have a line preserved by their symmetry groups. Other classes of two-orbit polyhedra that have been previously classified include the chiral (or type 2) polyhedra,...

Relativistic X-ray scattering factors are reported for a broad and systematically defined set of chemically relevant atomic anions, including mono- and multivalent species, for elements with atomic numbers Z = 1-85 [Greenwood & Earnshaw (19...

Polytypes can occur in many inorganic and organic compounds alike. In the most basic scenario, different polytypes of a compound are based on translationally equivalent layers and two equivalent arrangements of adjacent layers. This means t...
The growth and structural characterization of a La0.67Sr0.33MnO3/BaTiO3 superstructure (superlattice) [0.03%]

Despite significant research, the surface properties of quasicrystals and their approximants are not yet fully understood. In this paper, buckminsterfullerene (C60 fullerene) is used as a probe to test the adsorption properties of the (010)...

Motivated by theoretically and experimentally observed structural phases with octagonal symmetry, we introduce families of octagonal tilings composed of three prototiles. These tilings are defined by substitution rules with inflation factor...

A technical correction and update of the widely used recipes by Becker & Coppens [Acta Cryst. (1974), A30, 129-147], for the estimation of primary and secondary extinction factors in perfect spherical crystallites or grains, is presented. I...

The space group of a crystal structure is usually given by augmented matrices representing the action as affine mappings on direct space, but can also be described by generators and defining relators, i.e. by a group presentation. Related t...

Given two unit cells, the problem of determining the best match of the lattice of one to the lattice of the other can require large numbers of trial transformations. We present a solution that requires only a limited number of trials. ...
