Hydrogen bonding in 2-carboxyanilinium dihydrogenphosphate

Abstract

The structure of the title compound, C7H8NO2+·H2PO4−, shows that a single proton transfer occurs. The anions and cations are held together via strong and short O—H...O hydrogen bonds, in addition to N—H...O interactions. The three‐dimensional complex network of hydrogen bonds ensures the cohesion of the ionic structure.

“…For background to inorganic-organic hybrid materials, see: Benali-Cherif, Allouche et al (2007); Benali-Cherif, Kateb et al (2007); Messai et al (2009); Cherouana et al (2003). Changes in illuminated volume were kept to a minimum, and were taken into account (Gö rbitz, 1999) by multi-scan interframe scaling.…”

“…Inorganic organic hybrid materials have been studied extensively because the blending of organic and inorganic components allows to the development of materials with novel properties. (Cherouana et al, 2003;Benali-Cherif, Allouche et al, 2007;Benali-Cherif, Kateb et al, 2007;Messai et al, 2009; In particular the family of material which combine nitrate anions with organic molecules such as aromatic and aliphatic aminoacids has been studied intensively due to their numerous uses in various fields such as biomolecular science, liquid crystals, catalysts and fuel cells.…”

“…hydrogen bonds are most predominant in determining the formation of secondary structure elements in proteins, basepairing in nucleic acids and their biomolecular interactions. This structure analysis of cytosinium hydrogenphosphite (I) was undertaken as part of a more general investigation into the nature of hydrogen bonding between organic bases or amino acids and inorganic acids in their crystalline forms (Messai et al, 2009;Benali-Cherif, Abouimrane et al, 2002;Benali-Cherif, Benguedouar et al, 2002;Benali-Cherif et al, 2007).…”
