The structure of 4-phenyl-piperazine-1-sulfonamide was determined by X-ray crystallography. The compound crystallized in a monoclinic system and was characterized as follows: P21/c, a = 24.1829(7), b = 9.5485(3), c = 9.7885(2)Å, β = 92.2337(16)°, Z = 8, V = 2258.55(11)Å3. The crystal structure was solved by direct methods and refined by full-matrix least-squares on F2 to final values of R1 = 0.0427 for 3206 reflections [I > 2σ(I)] and R1 = 0.0739, wR2 = 0.1083 for all the 4589 unique reflections. The crystal structure consists of layers of polar regions that enclose a sulfonamide function linked by hydrogen bonds and hydrophobic regions with π-π stacking interactions.
