title: Helical supramolecular assembly of N2,N2')bis[3-(morpholin-4-yl)propyl]-N1,N1'-(1,2-phenylene)dioxalamide dimethyl sulfoxide monosolvate.
abstract: In the title compound, C(24)H(36)N(6)O(6)·C(2)H(6)OS, the carbonyl groups are in an antiperiplanar conformation, with O=C-C=O torsion angles of 178.59 (15) and -172.08 (16)°. An intramolecular hydrogen-bonding pattern is depicted by four N-H...O interactions, which form two adjacent S(5)S(5) motifs, and an N-H...N interaction, which forms an S(6) ring motif. Intermolecular N-H...O hydrogen bonding and C-H...O soft interactions allow the formation of a meso-helix. The title compound is the first example of a helical 1,2-phenylenedioxalamide. The oxalamide traps one molecule of dimethyl sulfoxide through N-H...O hydrogen bonding. C-H...O soft interactions give rise to the two-dimensional structure.
