چکیده
The title dimethyl sulfoxide (DMSO) solvate, C(17)H(18)N(4)O(3)·C(2)H(6)OS, shows the disubstituted urea derivative to adopt an almost planar geometry (r.m.s. deviation for non-H atoms = 0.132 Å); the mol-ecule has non-crystallographic twofold mol-ecular symmetry. This conformation is stabilized by two intra-molecular O-H⋯N hydrogen bonds. The components of the crystal are connected by N-H⋯O hydrogen bonds, whereby both amine H atoms are connected to a DMSO O atom, and C-H⋯O contacts involving the DMSO H and urea carbonyl atoms, forming a supra-molecular chain along the c axis. The chains associate via C-H⋯π inter-actions.
