In the title compound, C18H21N3O2, the dihedral angle between the benzene rings is 68.85 (11)°. In the crystal, the mol-ecules are linked by C-H⋯O and N-H⋯O hydrogen bonds, as well as weak C-H⋯π contacts, forming a three-dimensional supra-molecular architecture.
In the title compound, C14H11FO2, the dihedral angles beteen the central C3O ketone residue and the fluoro- and hy-droxy-substituted benzene rings are 50.44 (9) and 12.63 (10)°, respectively. The planes of the benzene rings subtend a dihedral angle of 58.88 (9)° and an intra-molecular O-H⋯O hydrogen bond closes an S(6) ring. No directional inter-actions… (More)
In the title compound, C20H14F3NS2, the seven-membered thia-zepine ring adopts a slightly distorted twist-boat conformation. The mean plane of the five-membered thio-phene ring fused to the thia-zepine ring is twisted by 32.3 (3) and 55.6 (4)° from the benzene and phenyl rings, respectively. In the crystal, inversion dimers linked by pairs of weak C-H⋯N… (More)
In the title compound, C15H15N3S2, the central pyrazole ring adopts a twisted conformation on the -CH-CH2- bond. Its mean plane makes dihedral angles of 7.19 (12) and 71.13 (11)° with those of the thio-phene and toluene rings, respectively. The carbothi-amide group [C(=S)-N] is inclined to the pyrazole ring mean plane by 16.8 (2)°. In the crystal,… (More)
In the title compound, C17H13NO5, the coumarin ring system is essentially planar (r.m.s. deviation = 0.008 Å). The nitro-phenyl ring makes a dihedral angle of 25.27 (9)° with the coumarin ring plane. The nitro group is almost coplanar with the phenyl ring to which it is attached, making a dihedral angle of 4.3 (3)°. The eth-oxy group is inclined to the… (More)
In the title compound, C23H20F3N3O3S2, the benzo-imidazole unit makes dihedral angles of 5.02 (1) and 76.42 (1)°, respectively, with the pyridine and methyl-benzene rings; the dihedral angle between the pyridine and methyl-benzene rings is 72.19 (1)°. In the crystal, mol-ecules are connected by weak C-H⋯F, C-H⋯O and C-H⋯N hydrogen bonds. Weak C-H⋯π… (More)
In the title compound, C17H10F3NS, the dihedral angle between the fused benzo-thio-phene ring system (r.m.s. deviation = 0.042 Å) and the benzene ring is 29.78 (11)°. The crystal structure features C-H⋯F and very weak C-H⋯N hydrogen bonds, which generate (001) sheets.
The title compound, C8H6FNO2, is almost planar (r.m.s. deviation for the non-H atoms = 0.019 Å) and the conformation across the C=C bond is trans. The C and H atoms of the side chain are disordered over two sets of sites in a 0.56 (3):0.44 (3) ratio. In the crystal, mol-ecules are linked by C-H⋯O inter-actions, thus forming C(5) chains propagating in .
In the title compound, C16H16N2, the dihydro-pyrazole ring adopts a shallow envelope conformation, with the C atom bearing the phenyl group displaced by 0.298 (2) Å from the other atoms (r.m.s. deviation = 0.015 Å). The dihedral angles between the four near coplanar atoms of the central ring and the N- and C-bonded phenyl groups are 13.49 (13) and 82.22… (More)
In the title compound, C14H11FO2, the two benzene rings are not coplanar, with a dihedral angle of 57.45 (12)° between their planes. In the crystal, mol-ecules are linked by an O-H⋯O hydrogen bond, forming a 21 helical chain along the b axis.
