Exploring the persistence of the fluorinated thiolate 2,3,5,6-S(C6F4H-4) motif to establish πF–πF stacking in metal complexes: a crystal engineering perspective† π–π stacking interactions are versatile because they are involved in many processes, such as protein folding, DNA stacking, and drug recognition. However, from the point of view of crystal engineering, there is an incipient knowledge of its exploitation.

In the period between 2009 and 2015, several very high-energy (VHE >100 GeV) gamma-ray flaring events from the BL Lac object PKS 1424+240 were observed by the Cerenkov telescopes VERITAS and MAGIC. It had uncertain redshift (z) and using spectroscopical measurement, Paiano et al. (2017) found it to be z = 0.604.

AbstractThe new labdane-type diterpenoid, physaglutinic acid (1), was isolated from the hexane extract of Physalis glutinosa. This compound is the first succinyl labdane isolated from a Physalis species. The known constituents of this plant were identified as the labdanes 12-O-acetylphysacoztomatin (3), physacoztomatin (4) and 12-epi-nicandrodiol (6). The flavonol retusin (8) was also isolated from this species.

We analysed the ionised gas kinematics of the dwarf galaxy NGC 4214 using high resolution Fabry-Perot interferometry observations and present a set of narrowband images in the Hα, [S ii] λ6717 Å, [N ii] λ6584 Å and [O iii] λ5007 Å emission lines. The high-resolution Fabry-Perot observations of the Hα emission line, allowed us to derive the velocity field, the velocity dispersion σ, and the rotation curve of the galaxy.
