Cover illustration: This compound, C23H22O5, also known as Caloxanthone C, was isolated from the stem bark of Calophyllum soulattri collected from the Sri Aman district in Sarawak, Malaysia. It consists of four six-membered rings and a 2-methylbut-3-en-2-yl side chain. The tricyclic xanthone ring system is almost planar [maximum deviation 0.093 (2) Å]. The pyranoid ring is in a distorted boat conformation, and the 2-methylbut-3-en-2-yl side chain is in a synperiplanar conformation. In the crystal, molecules are linked by a C-H...O interaction, forming zigzag chains propagating in [010]. See Ee, Mah, Kwong, Teh, Mohamed Tahir & Silong [Acta Cryst. (2011). E67, o2607-o2608].

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.

Journal news

Acta E is now included in the Thomson Reuters Emerging Sources Citation Index.
