2-(Benzylsulfanyl)pyridine N-oxide
In the title compound, C(12)H(11)NOS, the dihedral angle between the oxopyridinium and phenyl rings is 58.40 (1)°. The crystal structure is stabilized by C-H⋯O hydrogen bonds, π-π stacking inter-actions involving the pyridinium rings [centroid-centroid distance = 3.6891 (9) Å] and C-H⋯π inter-actions.

In the title compound, C(16)H(19)NOS, the durene ring and the oxopyridyl ring form a dihedral angle of 82.26 (7)°. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds, weak C-H⋯π inter-actions and π-π inter-actions [centroid-centroid distance of 3.4432 (19) Å], together with intra-molecular S⋯O [2.657 (2) Å] short contacts.
متن کامل2-(Mesitylmethylsulfanyl)pyridine N-oxide monohydrate
In the title compound, C(15)H(17)NOS·H(2)O, the benzene and pyridine rings form a dihedral angle of 71.18 (2)°. The intra-molecular S⋯O distance [2.737 (3) Å] is shorter than expected and, in terms of hybridization principles, the N-C-S angle [114.1 (2)°] is smaller than expected. The crystal structure is stabilized by inter-molecular O-H⋯O and weak C-H⋯O hydrogen bonds. In addition, weak π-π s...
متن کامل2-[(6-Bromo-2-pyridyl)amino]pyridine N-oxide
In the crystal structure of the title compound, C(10)H(8)BrN(3)O, the dihedral angle between the two pyridine rings is 2.48 (2)°. A weak intramolecular N-H⋯O hydrogen bond is present.
متن کامل2-(Mesitylmethylsulfanyl)pyridine N-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...
