Investigation of hydrogen bonding patterns in a series of multi-component molecular solids formed by tetrabromoterephthalic acid with selected N-heterocycles

Abstract

Hydrogen bonding patterns in a series of multi-component molecules constructed by tetrabromoterephthalic acid with N-heterocycles are discussed in this study.

“Anti‐electrostatic” Halogen Bonding between Ions of Like Charge

“…Consequently, the atoms involved in these XB contacts are commonly halogen or oxygen atoms. Interestingly, the XB contacts involved, in some cases, dianions despite their seemingly even more repulsive charges (see for example, 10 [31] and 11 [32] in Figure 7 , left; see Supporting Information for more details).…”

The crystal structure of 2,4-dimethylimidazole monohydrate, C5H10N2O

“…As the onset of the changed behaviour coincided with an older batch of the reagent being used in our laboratories, the nature of the compound was checked by means of a diffraction study. Structural information about the title compound acting as a cation is apparent in the literature [12,13].…”
