Abstract: In the crystal structure of the title compound, 4C₂₁H₂₂N₂O₂S₂·0.5C₃H₆O·11.5H₂O, there are four crystallographically independent molecules (A, B, C, D) with similar geometries, 11 water molecules and a solvent acetone molecule which is disordered with a water molecule with occupancy factors of 0.5:0.5. The dihedral angles formed by the mesitylene ring with the two pyridyl rings are 82.07 (3) and 78.39 (3)° in molecule A, 86.20 (3) and 82.29 (3)° in molecule B, 81.05 (3) and 76.0 (4)° in molecule C, 86.0 (3) and 80.9 (3)° in moleule D. The two pyridyl rings form dihedral angles of 41.17 (4), 64.01 (3), 81.9 (3) and 82.25 (3)° in molecules A, B, C and D, respectively. The crystal structure is stabilized by intermolecular O-HO hydrogen bonds and possible weak C-H interactions. Some short intramolecular SO contacts are apparent [2.684 (4)-2.702 (4) Å].
