4-Sulfamoylanilinium nitrate

Abstract

In the crystal structure of the title compound, C6H9N2O2S+·NO3 −, the cations and anions are connected by N—H⋯O hydrogen bonds into a three-dimensional network.

4-Sulfamoylanilinium perchlorate

“…The protonation on the one of N sites is confirmed from C-N bond distance. The geometrical parameters of the cation are in agreement with the reported sulfomylanilinium structures in 4-sulfomylanilinium nitrate (Pandiarajan et al, 2011) and Bis(4-sulfomylanilinium) sulfate (Ravikumar et al, 2013). hydrogen bonds is observed to be bifurcated hydrogen bond, with one donor hydrogen (Table 1)…”

“…The uses of Sulfanilamide, was started during 1936 (Buttle et al, 1936) and the grandparent of the sulfonamide family of drugs that are still in use today. The nitrate and sulfate complexes of sulfanilamide (Pandiarajan et al, 2011;Ravikumar et al, 2013) were already reported. In continuation of our interest on the sulfanilamide complexes, the synthesis of the title compound and its title structure,bis(4-sulfamoylanilinium) sulfate, is described here.…”

“…For the first use of sulfanilamide, see: Buttle et al (1936). For related structures, see: Ravikumar et al (2013); Pandiarajan et al (2011); Topacli & Kesimli (2001). For graph-set motifs, see Etter et al (1990).…”

Crystal structure of 4-sulfamoylanilinium dihydrogen phosphate

“…The perchlorate (Anitha, et al, 2013); nitrate, (Pandiarajan, et al, 2011); sulfate (Ravikumar et al, 2013) and hydrogen chloride (Zaouali Zgolli et al, 2010) complexes of sulfanilamide were already been reported. The present report on phosphate salt of sulfanilamide is part of a series of x-ray investigations being carried out on sulfanilamide-inorganic acid complexes.…”
