Structure of 4-homosulfanilamide hydrochloride

Abstract

STRUCTURE OF 4-HOMOSULFANILAMIDE HYDROCHLORIDEmolecules are stacked roughly parallel to the ab plane at average intervals of 3.9 A and there is a distinct overlap of the benzene rings in the z direction.

4-Sulfamoylanilinium nitrate

“…The protonation on the one of the N sites is confirmed from C-N bond distance. The other geometrical parameters of the cation are in agreement with the reported structures of 4-homosulfanilamide hydrochloride (Chatterjee et al, 1981), 4aminobenzenesulfonamide (Gelbrich et al, 2008), bis(4-Aminosulfonyl)benzeneammonium hexafluorosilicate (Gelmboldt et al,2004), 4-sulfonamidoanilinium 3,5-dinitrosalicylate (Smith et al, 2001) and 4-sulfamoylanilinium chloride (Zaouali Zgolli et al, 2010).…”

Structural studies on molecular complexes. II. Structure of aminacrine–sulfadimidine (1/1)

“…The S-N and N-C bonds are amongst the shortest when compared with the values in related compounds (Shefter, Chmielewicz, Blount, Brennan, Sackman & Sackman, 1972;Chatterjee, Dattagupta & Saha, 1981, 1982 while the S-C and S-O bonds are amongst the longest of those observed in related compounds. The endocyclic angle at C(27) is 121.9 (3) °, and is within the normal range observed in sulfonamides with a pyrimidine ring.…”

The Legacy of G. N. Ramachandran and the Development of Structural Biology in India

“…Those who then effectively used the data included R. Srinivasan of the Madras University 32,33 , to start with, among others [34][35][36][37] . Substantial progress was made during this phase in the crystallography of amino acids and peptides [38][39][40][41][42][43] , including the relevance of their supramolecular association to chemical evolution and origin of life 44 , nucleic acids and their constituents 45 , ionophores and related compounds 46,47 , and medicinally important molecules [48][49][50] . The same is true about NMR studies on medium-sized biomolecules [51][52][53] .…”
