Bis(2-aminopyridinium) sulfate

Abstract

In the structure of the title compound, 2C5H7N2 +·SO4 2−, the S atom of the sulfate anion lies on a twofold axis. The structure is stabilized by an extensive network of N—H...O hydrogen bonds.

2-Aminopyridinium nitrate

“…The crystal structure of the sulfate salt of 2-aminopyridinium has been reported previously (Jebas et al, 2006), and appears to be the only report in the literature of a structure consisting of 2aminopyridinium cations and non-metallic inorganic anions. The crystal structure of the sulfate salt of 2-aminopyridinium has been reported previously (Jebas et al, 2006), and appears to be the only report in the literature of a structure consisting of 2aminopyridinium cations and non-metallic inorganic anions.…”

“…The structure of 2-aminopyridinium nitrate, (I), was determined as part of an ongoing study of the structural characteristics of organic-inorganic hybrid materials. The crystal structure of the sulfate salt of 2-aminopyridinium has been reported previously (Jebas et al, 2006), and appears to be the only report in the literature of a structure consisting of 2aminopyridinium cations and non-metallic inorganic anions.…”

Synthesis, structure and characterization of five new organically templated metal sulfates with 2-aminopyridinium

“…In the case of double metal and 2ap sulfates, only one representative is known up to now, namely bis(2-aminopyridinium) hexaaquacopper(II) bis-(sulfate) tetrahydrate (Lukianova et al, 2015). The crystal structure of bis(2-aminopyridinium) sulfate has also been reported (Jebas et al, 2006a). In the literature, there are reports where simple inorganic-organic hybrids with the 2ap cation and various halogen salts, characterized by interesting supramolecular networks (Luque et al, 1997;Su et al, 2002;Kumar et al, 2005;Jebas et al, 2006b;Zhang et al, 2006;Fun et al, 2008;Gelmboldt et al, 2009;Cai & Fu, 2010;Jin et al, 2011;Rao et al, 2011;Mhadhbi et al, 2016) and dielectric properties, are discussed (Kulicka et al, 2004).…”

2-Aminopyridinium 2-methoxycarbonyl-4,6-dinitrophenolate

“…The structures of many molecular proton transfer adducts containing substituted pyridinium and an acid anion have been reported in the past decades (Gellert & Hsu, 1988;Smith et al, 2000;Jebas et al, 2006;Rademeyer, 2007;Hemamalini & Fun, 2010a,b, c). As a substituted pyridinium, 2-aminopyridine has attracted great attention due to its various hydrogen bonds (Gellert & Hsu, 1988;Jebas et al, 2006;Perpétuo & Janczak, 2010;Hemamalini & Fun, 2010a). We report here the synthesis and crystal structure of 2-aminopyridinium 3,5-dinitromethyl salicylate (I).…”
