Highlighted illustration

Cover illustration: Perhaps as a result of its highly deliquescent nature, the X-ray crystal structure of trichloroacetic acid has not been reported until now. This low-temperature study reveals that the molecules form centrosymmetric pairs, leading to hydrogen-bonded dimers. See Rajagopal, Mostad, Krishnakumar, Subha Nandhini & Natarajan [Acta Cryst. E59, o316-o318].

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.
