title: Intermolecular contacts in the crystal packing of 2,2'-(N,N'-oxalyldiimino)bis(3-phenylpropanamide) dimethyl sulfoxide solvate.
abstract: In the title compound, C20H22N4O4*C2H6OS, two distinct hydrogen-bond systems connect oxalamide groups in one pattern and primary amide groups in the other to form a two-dimensional network perpendicular to the c axis. These hydrophilic layers are joined to the three-dimensional structure through C--H...pi interactions. The hydrogen-bonded waved layers shape holes which are occupied by disordered dimethyl sulfoxide solvent molecules.
