2-(4-Methoxyphenyl)-4H-1,3,2-benzoxathiaphosphinine 2-sulfide
The asymmetric unit of the title compound, C14H13O2PS2, contains two crystallographically independent molecules, which differ in the conformation of the 1,3,2-benzoxathiaphosphinine moieties (screw boat in the first molecule and envelope in the second molecule). In the crystal, neither classical nor non-classical hydrogen bonds are found. Weak interactions (about 2.9–3.0 Å) between the lone pair of the terminal S atoms with H atoms occur. This compound was further characterized by 1H NMR and IR spectroscopy
2-[2-(1H-Imidazol-1-yl)-2-adamantyl]phenol
In the title molecule, C19H22N2O, the imidazole and benzene rings form a dihedral angle of 84.53 (5)°. In the crystal, classical intermolecular O—H⋯N hydrogen bonds pair the molecules into centrosymmetric dimers, and C—H⋯π interactions further link these dimers into columns propagated in [100]
4-Allyl-3-(2-methyl-4-quinolyl)-1H-1,2,4-triazole-5(4H)-thione
In the title compound, C15H14N4S, the quinoline and triazole rings form a dihedral angle of 41.48 (7)°. In the crystal, adjacent molecules are linked by N—H⋯N hydrogen bonds, forming chains along [100]
Methyl 4-methyl-2-oxo-1,2,5,6-tetrahydro-4H-pyrrolo[3,2,1-ij]quinoline-6-carboxylate
In the title molecule, C14H15NO3, the six-membered heterocyclic ring exhibits an envelope conformation. In the crystal, C—H⋯π interactions link the molecules into centrosymmetric dimers, and weak intermolecular C—H⋯O hydrogen bonds link these dimers into columns propagated along [100]
