Structure of N,N′-bis[3-(aminocarbonyl)propyl]sulfamide

The title compound, C₈H₁₈N₄O₄S, possesses C₂ symmetry, with the S atom lying on a twofold rotational axis in the unit cell. The sulfamide group of each molecule forms four identical hydrogen bonds with those of its four neighboring molecules, resulting in a rhombic two-dimensional hydrogen bonded network. This network assembles in the third dimension via hydrogen bonds between the primary amide groups of the substituents that extend from the 2D sulfamide sheets. The primary amide groups form a hydrogen-bonded eight-membered cyclic dimer around a two-fold rotational axis. These cyclic dimers are linked into a ribbon-like network via hydrogen bonding interaction between the trans-H and the carbonyl of the amide groups. The compound crystallizes in C2/ca with a = 8.6162(1), b = 57716(1), c = 24.8344(b) Å, β = 96.298(1)°, D_calc = 1.441 g cm^-3, and Z = 4.
