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]
