6-Chloroquinolin-2(1H)-one
In the title compound, C(9)H(6)ClNO, the Cl atom deviates by 0.142 (1) Å from the quinoline ring mean plane (r.m.s. deviation = 0.013 Å). In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into [010] C(4) chains. Aromatic π-π stacking inter-actions [shortest centroid⋯centroid distance = 3.685 (3) Å] are also observed.

In the title compound, C(18)H(16)N(2)O(2), the central pyridazine ring forms dihedral angles of 77.08 (5)° and 84.62 (5)° with the two benzene rings. The dihedral angle between the two benzene rings is 68.18 (4)°. A very weak intra-molecular C-H⋯N hydrogen bond and an intra-molecular C-H⋯π inter-action occur. The crystal structure is stabilized by weak inter-molecular C-H⋯O hydrogen bonds and w...
متن کامل2-(4-Chlorophenyl)-6-methoxychroman-4-one
In the title mol-ecule, C(16)H(13)Cl O(3), the two aromatic rings form a dihedral angle of 65.3 (1)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers, which are further packed into columns propagating in [100] by weak C-H⋯π inter-actions.
متن کامل6-Hydroxy-5,7,8-trimethylchroman-2-one
The title compound, C(12)H(14)O(3), consists of a chromanone unit with an -OH substituent at the 4-position and methyl substituents on the remaining C atoms of the aromatic ring. The fused pyran-one ring adopts a distorted envelope conformation with the methyl-ene group adjacent to the carbonyl carbon as the flap atom. The crystal structure is stabilized by classical O-H⋯O hydrogen bonds and we...
متن کامل6-Hydroxy-7,8-dimethylchroman-2-one
The title compound, C(11)H(12)O(3), is essentially planar, with an r.m.s. deviation of 0.179 Å from the mean plane through the 14 non-H atoms in the mol-ecule. The benzene ring and the pyranone mean plane are inclined at 13.12 (6)° to one another and the pyran-one ring adopts a flattened chair conformation. In the crystal, O-H⋯O hydrogen bonds and C-H⋯O contacts form R(1) (2)(6) rings and link ...
