Highlighted illustration

Cover illustration: This seven-coordinate W compound can be described as a 4:3 piano-stool arrangement, with the three carbonyl ligands forming the legs of the stool. The other four N and S atoms bonded to W form the distorted square base of the piano-stool. See Esterhuysen et al. [Acta Cryst. E57, m72-m74].

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.
