More statistics on intermetallic compounds - ternary phases

J. Dshemuchadse and W. Steurer

Synopsis: Ternary intermetallics - 13 026 compounds contained in the database Pearson's Crystal Data - are discussed with respect to their components, structure types and stoichiometries.

V. M. Talanov, V. B. Shirokov and M. V. Talanov

Icosahedral symmetry breaking: C60 to C84, C108 and to related nanotubes

M. Bodner, E. Bourret, J. Patera and M. Szajewska

Synopsis: The structure of a particular type of hollow-cage higher fullerene (C60+N24) is described and their construction explained from a symmetry-breaking mechanism starting from perfect icosahedral symmetry of C60 to specific subgroups A1 × A1. This mechanism expands and completes previous results describing the existence of other groups of fullerenes (C60+N10, C60+N18) based on the breaking of icosahedral symmetry of C60 to the subgroups H2 and A2. The mechanism is extended to describe the cases that generate carbon nanotubes.

Determination of small crystal structures from a minimum set of diffraction intensities by homotopy continuation

D. Leggas and O. V. Tsodikov

Synopsis: A method from numerical algebraic geometry, called homotopy continuation, is used to determine small crystal structures of four or fewer atoms directly from a minimum set of diffraction intensities.


Accepted 12 February 2015

Magnetic structure determination from the magnetic pair distribution function (mPDF): ground state of MnO

B. A. Frandsen and S. J. L. Billinge

Synopsis: Combined atomic and magnetic pair distribution function (PDF) refinements have been performed against neutron scattering data from MnO, recovering the expected long-range-ordered antiferromagnetic state and supporting a scenario of monoclinic symmetry on a local length scale of ~100 Å. This represents the first experimental application of the magnetic PDF method.
