1-(2-Methyl-6-nitro-4-phenyl-3-quinolyl)ethanone
In the title compound, C(18)H(14)N(2)O(3), the quinoline ring system is almost planar [maximum deviation = 0.013 (2) Å] and forms a dihedral angle of 60.36 (7)° with the benzene ring. The nitro group is slightly twisted from the attached quinoline ring system, forming a dihedral angle of 9.06 (19)°. In the crystal packing, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into chains pro...
متن کامل(E)-3-(2-Chloro-6-methyl-3-quinolyl)-1-(2,3-dihydro-1,4-benzodioxin-6-yl)prop-2-en-1-one
In the title mol-ecule, C(21)H(16)ClNO(3), the quinoline and benzene rings are inclined at 56.96 (6)° with respect to each other and the dioxine ring is in a twist-chair conformation. The structure is devoid of any classical hydrogen bonds. Rather weak inter-molecular hydrogen-bonding inter-actions of the types C-H⋯N and C-H⋯O are present, consolidating the crystal structure.

The asymmetric unit of the title compound, C(17)H(14)O(6)S, contains four crystallographically independent mol-ecules in which the pyran-one units are essentially planar, with maximum deviations of 0.016 (2), 0.019 (2), 0.025 (2), 0.014 (2), 0.020 (2), 0.010 (2), 0.003 (2) and 0.012 (2) Å. One of the thio-phene rings is disordered over two positions, with an occupancy ratio of 0.739 (4):0.261 (...
متن کامل3-Methyl-1-(prop-2-en-1-yl)quinoxalin-2(1H)-one
In the mol-ecule of the title compound, C(12)H(12)N(2)O, the quinoxaline ring is planar with an r.m.s. deviation of 0.007 (15) Å. The dihedral angle between the quinoxaline and propenyl planes is 82.1 (2)°. The crystal packing is stabilized by offset π-π stacking between the quinoxaline rings [centroid-centroid distance = 3.8832 (9) Å].
متن کامل(2E)-3-(2-Chloro-6-methyl-3-quinolyl)-1-(1-naphthyl)prop-2-en-1-one
In the title mol-ecule, C(23)H(16)ClNO, the quinoline and naphthalene ring systems are individually planar, with maximum deviations of 0.020 (2) and 0.033 (2) Å, respectively, and are inclined at a dihedral angle of 30.01 (4)°. Intra-molecular C-H⋯O and C-H⋯Cl inter-actions occur. The crystal structure is devoid of any classical hydrogen bonds, but symmetry-related mol-ecules are linked via wea...
