4-Methyl-1-phenylquinolin-2(1H)-one
In the title compound, C(16)H(13)NO, the mol-ecules are connected three-dimensionally through non-classical C-H⋯O and C-H⋯π inter-actions of 3.272 (3), 3.380 (3) and 3.382 (4) Å. Classical hydrogen bonds are not observed. The dihedral angle between the benzyl and quinolin-2(1H)-one mean planes is 87.15 (7)°
متن کامل2-(4-Chlorophenyl)-4-[1-(4-chlorophenyl)-3-methyl-1H-pyrazol-5-yl]-5-methyl-1H-pyrazol-3(2H)-one
The title compound, C(20)H(16)Cl(2)N(4)O, has two mol-ecules in the asymmetric unit. The two five-membered rings form a dihedral angle of 54.2 (3)° in one mol-ecule and 56.8 (3)° in the other independent mol-ecule. The amino group of the dihydro-pyrazolone unit of one mol-ecule acts as a hydrogen-bond donor to the carbonyl group of the dihydro-pyrazolone system of the other mol-ecule. The resul...

The title mol-ecule, C(5)H(7)N(3)O(2), has an almost planar conformation, with a maximum deviation of 0.043 (3) Å, except for the methyl H atoms. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into layers parallel to the bc plane. Inter-molecular π-π stacking inter-actions [centroid-centroid distances = 3.685 (2) and 3.697 (2) Å] are observed between the para...

In the title compound, C15H15N3O2S, the fused ring system is close to planar, the largest deviation from the mean plane being 0.030 (2) Å, and makes a dihedral angle of 48.84 (9)° with the benzene ring belonging to the methyl-benzene-sulfonamide moiety. In the crystal, mol-ecules are -connected through N-H⋯N hydrogen bonds and weak C-H⋯O contacts, forming a two-dimensional network parallel to (...
متن کاملN′-[1-(4-Chlorophenyl)ethylidene]-5-methyl-1-(4-nitrophenyl)-1H-1,2,3-triazole-4-carbohydrazide
In the title compound, C(18)H(15)ClN(6)O(3), the 1,2,3-triazole ring forms dihedral angles of 15.64 (5) and 57.50 (5)° with the two benzene rings. The dihedral angle between the two benzene rings is 72.26 (5)°. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds into chains propagating along the b axis. A short O⋯C contact of 2.9972 (13) Å is observed.
