Electronic Properties of Molecules and Surfaces with a Self\uad-Consistent Interatomic van der Waals Density Functional. [PDF]

open access: yes, 2015
How strong is the effect of van der Waals (vdW) interactions on the electronic properties of molecules and extended systems? To answer this question, we derived a fully self-consistent implementation of the density-dependent interatomic vdW functional of

Crystal structure and Hirshfeld surface analysis of 8-azaniumylquinolinium tetrachloridozincate(II)

open access: yesActa Crystallographica Section E Crystallographic Communications, 2023
The reaction of 8-aminoquinoline, zinc chloride and hydrochloric acid in ethanol yielded the title salt, (C9H10N2)[ZnCl4], which consists of a planar 8-azaniumylquinolinium dication and a tetrahedral tetrachlorozincate dianion. The 8-aminoquinoline moiety is protonated at both the amino and the ring N atoms.

2-[(1E)-({[(Benzylsulfanyl)methanethioyl]amino}imino)methyl]-6-methoxyphenol: crystal structure and Hirshfeld surface analysis

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2016
The title dithiocarbazate ester, C16H16N2O2S2, comprises two almost planar residues, i.e. the phenyl ring and the remaining 14 non-H atoms (r.m.s. deviation = 0.0410 Å). These are orientated perpendicularly, forming a dihedral angle of 82.72 (5)°.
