| Summary: | The title dimethyl sulfoxide (DMSO) solvate, C17H 18N4O3·C2H6OS, 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. |
