In the structure of the title compound, C₂₃H₂₀ClN₅O₄S₂·2C₂H₆OS, the two DMSO solvent mol-ecules are hydrogen bonded to the two NH groups of the main mol-ecule. The (modified) triazine ring is planar and is approximately perpendicular to its directly bonded meth-oxy-phenyl substituent. The bond lengths and angles indicate extensive delocalization of the multiple bonding. The packing is characterized by a large number of borderline contacts, especially 'weak' hydrogen bonds. There is no π-π stacking. The centroid of the triazine ring is involved in two short contacts, namely 2.63 Å to a phenyl hydrogen atom and 3.0509 (9) Å to a meth-oxy oxygen atom.
