4-Sulfamoylanilinium perchlorate

In the crystal of the title salt, C(6)H(9)N(2)O(2)S(+)·ClO(4) (−), the components are linked by N—H⋯O hydrogen bonds, forming a three-dimensional network. The cations are connected along a and b axes, leading to linear and zigzag C(3) and C(8) chain motifs, respectively. A cation–anion inter­action along the c axis leads to a C (2) (2)(12) chain motif. R (3) (3)(18) and R (3) (3)(20) ring motifs are observed as cation–anion-type inter­actions. These hydrogen-bonding ring and chain motifs are localized at z = 0 or 1, leading to alternate hydro­philic and hydro­phobic regions along the c axis as a result of the stacking of anions and the aromatic cationic parts.
