2-(2,3,5,6-Tetramethylbenzylsulfanyl)pyridine N-oxide
In the title compound, C16H19NOS, the durene ring and the oxopyridyl ring form a dihedral angle of 82.26 (7)°. The crystal structure is stabilized by intermolecular C—H...O hydrogen bonds, weak C—H...π interactions and π–π interactions [centroid–centroid distance of 3.4432 (19) Å], together with intramolecular S...O [2.657 (2) Å] short contacts.
catena-Poly[[aquasodium(I)]-μ-[2,2′-(disulfanediyl)bis(pyridineN-oxide)]-μ-(pyridine-2-thiolato 1-oxide)]
There are two monomeric units in the asymmetric unit of the polymeric title compound, [Na(C(5)H(4)NOS)(C(10)H(8)N(2)O(2)S(2))(H(2)O)](n). The Na(I) ions are six coordinated by four O atoms, one S atom and one water mol-ecule, forming a slightly distorted octa-hedral geometry. An intra-molecular O-H⋯O hydrogen bond stabilizes the conformation of the mol-ecule. The crystal packing is consolidated by inter-molecular O-H⋯O, O-H⋯N and O-H⋯S hydrogen bonds, π-π inter-actions [with centroid-centroid distances of 3.587 (2) Å] together with weak C-H⋯π inter-actions. The mol-ecules are linked into polymeric chains along the b-axis direction.
2-(Mesitylmethylsulfanyl)pyridineN-oxide–18-crown-6 (2/1)
In the title compound, 2C(15)H(17)NOS·C(12)H(24)O(6), 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 ethyl-eneoxy 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 inter-actions.
