Rationalising molecular crystal structures using Hirshfeld surfaces [PDF]

open access: yesActa Crystallographica Section A Foundations and Advances, 2014
Hirshfeld surface analysis [1] has very quickly become a routine tool for rationalising and visualising intermolecular interactions in crystals. The serendipitous discovery of an intriguing and novel way to identify the space `belonging' to a molecule in a crystal has led to the development of a suite of computational tools that facilitate a deeper ...

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.
