Highlighted illustration

Cover illustration: Crystallographic characterization of this side product of a coupling reaction required synchrotron radiation in view of the weak diffraction from small crystals, which appear to be hollow in a scanning electron micrograph. [pi] - [pi] and nitro- [pi] stacking interactions are found in the crystal structure. See Kaafarani, Wex, Oliver, Krause Bauer & Neckers [Acta Cryst. E59, o227-o229].

Research communications

The first papers in this new format were published in July 2014. Research communications are longer papers with new text sections designed to help authors bring out the science behind their structure determinations. Figures are included in the published paper and, for the first time in Acta E, individual reports are not limited to single structure determinations. The Research communications format will make Acta E the natural home for structure determinations with interesting science to report.
