The syntheses and crystal structures of six substituted benzenesulfonyl-asparagine derivatives are reported. Despite showing three different unit cells and crystal symmetries, the molecular conformations and robust packing motifs are essentially the same in the six structures. In each case, [010] chains in which adjacent molecules are linked by three N-H· · · O hydrogen bonds are crosslinked by O-H· · · O hydrogen bonds to generate (001) sheets. Weak inter-sheet π-π interactions occur in some of the structures.
