Structures of the ZrZn22 family: suprapolyhedral nanoclusters, methods of self-assembly and superstructural ordering
G. D. Ilyushin and V. A. Blatov
Synopsis: A number of strict rules are proposed to model the crystal structures of intermetallics as a network of cluster precursors. According to these rules the self-assembly of the ZrZn22-like structures was considered within the hierarchical scheme: primary polyhedral clusters (one AX16 + 2BX12) zero-dimensional nanocluster precursor (AB2X37) one-dimensional primary chain two-dimensional microlayer three-dimensional microframework (three-dimensional supraprecursor).

Unusual hydrogen atom display in solid acids
B. V. Merinov
Synopsis: An unusual display of dynamically disordered H atoms with low position occupancies is observed in electron-density maps of the superprotonic phases of solid acids.

SiBr4 - prediction and determination of crystal structures
A. K. Wolf, J. Glinnemann, M. U. Schmidt, J. Tong, R. E. Dinnebier, A. Simon and J. Kohler
Synopsis: For SiBr4 crystal structures were predicted by global lattice-energy minimizations. Two predicted structures could be verified experimentally.

Accepted 27 March 2009
Review of complex ceramic structures. I. Weberites
L. Cai and J. C. Nino
Synopsis: This is a review of weberite ceramics. The structural features of weberite, its relationship to the fluorite and the pyrochlore structures, and some weberite ceramics with interesting properties are reviewed.

Structures of K0.05Na0.95NbO3 (50-300 K) and K0.30Na0.70NbO3 (100-200 K)
N. Zhang, A. M. Glazer, D. Baker and P. A. Thomas

Accepted 9 March 2009
On the correlations between the polyhedron eccentricity parameters and the bond-valence sums for the cations with one lone electron pair. Addendum
V. Sidey
Synopsis: Systematic variations of the bond-valence sums calculated from the poorly determined bond-valence parameters have been illustrated using a simple graphical scheme.

Charge density and electrostatic potential analyses in paracetamol
N. Bouhmaida, F. Bonhomme, B. Guillot, C. Jelsch and N. E. Ghermani
Synopsis: The charge density of the monoclinic paracetamol drug has been derived from high-resolution X-ray diffraction. Topological features of the electron density and electrostatic potential are presented.

Accepted 19 February 2009
Absolute structure determination as a reference for the enantiomeric resolution of racemic mixtures of cyclophosphazenes via chiral high-performance liquid chromatography
S. Coles, D. Davies, M. Hursthouse, S. Yesilot, B. Cosut and A. Kilic
Synopsis: The absolute configurations of pairs of enantiomers separated by high-performance liquid chromatography have been confirmed by single-crystal structure analysis and provide a reference system for subsequent assignment of such systems based on elution order. The solid-state structures of the pairs of enantiomers do not fully adhere to expected enantiomorphous crystallization behaviour.
