Tetra­kis{2,4-bis­[(1-oxo-2-pyridyl)­sulfanyl­methyl]mesitylene} acetone hemisolvate 11.5-hydrate

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—H⋯O hydrogen bonds and possible weak C—H⋯π inter­actions. Some short intra­molecular S⋯O contacts are apparent [2.684 (4)–2.702 (4) Å]

2-(Mesitylmethyl­sulfan­yl)pyridine N-oxide–18-crown-6 (2/1)

In the title compound, 2C15H17NOS·C12H24O6, the asymmetric unit consists of one N-oxide derivative and one-half of the 18-crown-6 ether, which lies on an inversion centre. In the crown ether, the O—C—C—O torsion angles indicate a gauche conformation of the ethyl­eneoxy units, while the C—O—C—C torsion angles indicate planarity of these segments. In the N-oxide unit, the dihedral angle between the pyridine and benzene rings is 85.88 (12)°. The crystal packing is stabilized by weak C—H⋯O hydrogen bonds and C—H⋯π inter­actions

catena-Poly[[aqua­sodium(I)]-μ-[2,2′-(disulfanedi­yl)bis­(pyridine N-oxide)]-μ-(pyridine-2-thiol­ato 1-oxide)]

There are two monomeric units in the asymmetric unit of the polymeric title compound, [Na(C5H4NOS)(C10H8N2O2S2)(H2O)]n. The NaI ions are six coordinated by four O atoms, one S atom and one water mol­ecule, forming a slightly distorted octa­hedral geometry. An intra­molecular O—H⋯O hydrogen bond stabilizes the conformation of the mol­ecule. The crystal packing is consolidated by inter­molecular O—H⋯O, O—H⋯N and O—H⋯S hydrogen bonds, π–π inter­actions [with centroid–centroid distances of 3.587 (2) Å] together with weak C—H⋯π inter­actions. The mol­ecules are linked into polymeric chains along the b-axis direction

2,4,6-Tris(1-oxo-2-pyridylsulfanylmeth­yl)mesitylene methanol solvate

Intra­molecular C—H⋯S hydrogen bonds generate S(6) ring motifs. The crystal structure is stabilized by intra­molecular C—H⋯S and inter­molecular C—H⋯O hydrogen bonds and weak C—H⋯π inter­actions
