2-Methyl-4-oxopentan-2-aminium 2-sulfamoylbenzoate

In the title salt, C6H14NO+·C7H6NO4S−, the 2-sulfamoylbenzoate anion has two intramolecular hydrogen bonds, forming a five membered C—H...O and a seven-membered N—H...O twisted ring with ring motifs S(5) and S(7), respectively, while the 2-methyl-4-oxopentan-2-aminium cation also has a stabilizing intramolecular N—H...O hydrogen bond with a twisted S(6) ring motif. The anions form inversion-related dimers with R22(8) ring motifs through intermolecular N—H...O hydrogen bonding. The dimers and cations are further linked and stabilized through intermolecular N—H...O and C—H...O bonds, forming zigzag-shaped layers that extend along the crystallographic a axis
