High-Pressure Diffraction Frolic-Goats Workshop

Poznań, Poland, April 2014

The 7th High-Pressure Diffraction Frolic-Goats Workshop (FgHp-7) 2014 was held in the Faculty of Chemistry, Adam Mickiewicz U. in Poznań, Poland, 27-29 April 2014. 34 participants from 8 countries attended. FgHp-7 was designed to disseminate information on high-pressure techniques, mainly X-ray diffraction single-crystal diffractometry using a diamond-anvil cell (DAC), among crystallographers, chemists and physicists. Other techniques, such as high-pressure volumetric measurements, were presented. The lectures were focused on the methodology of high-pressure diffraction experiments and their application: 'Advancements and experimental experiences in sXRD at non-ambient conditions' (R. Miletich), 'Pressure-induced changes in pyrimidine aggregation' (E. Patyk), 'Studies on haloimidazoles' (M. Andrzejewski), 'High-pressure studies on 2,4,5-tribromo- and 2,4,5-trichloroimidazole' (K. Rajewski), 'Oscillation frequencies of molecules in liquids and high-pressure crystal structures' (J. Bąk), 'Structural and Electronic Properties in two-dimensional layered metal chalcogenides' (A. Andrada), 'Mandelic Acid versus the Wallach’s Rule' (J. Marciniak), 'Negative area compressibility in 2-methylbenzimidazole' (W. Zieliński), 'Reversed negative linear compressibility of a nonlinear-optics organic crystal 3-methyl-4-nitropyridine N-oxide' (W. Cai) and 'High-pressure experiments and data reduction with CrysAlis' (M. Meyer). The CrystEngComm Poster Prize was awarded to H. Tomkowiak for 'Short-range interactions of organic compounds at high pressure'. The third day of the Workshop was dedicated to practical exercises on the DAC operation, alignment, loading, isochoric crystallization, and processing the diffraction data. The operation of the piston-and-cylinder press for compressibility measurements was demonstrated. The Workshop excursion and get-together were organized in Fort No. 3 (located at the centre of the New Poznań Zoo), one of 18 forts surrounding Poznań in the 19th century, then one of the largest strongholds in Prussia. The FgHp-7 Workshop was sponsored by the Faculty of Chemistry, Adam Mickiewicz U. and Agilent Technologies, and was organized by the Team supported by the Foundation for Polish Science.
