In the title compound, C27H21N3O6·C2H5OH, the indole ring systems are approximately perpendicular to each other, with a dihedral angle of 89.3 (5)°; the plane of the benzene ring is oriented with respect to the indole ring systems at 49.9 (5) and 73.4 (3)°. In the crystal, mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds and weak C-H⋯π inter-actions(More)
In the title compound, C(10)H(6)FNO(2)S, the benzene and thia-zolidine rings make a dihedral angle of 7.52 (3)°. Intra-molecular C-H⋯O and C-H⋯S hydrogen bonds result in the formation of nearly planar five- and six-membered rings; the adjacent rings are nearly coplanar. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules.
In the title compound, C11H8N2O2S, the oxadiazinone ring is nearly planar [maximum deviation = 0.016 (4) Å], and is approximately coplanar with the benzo-thio-phene ring system [dihedral angle = 3.1 (5)°]. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, forming chains running along the b-axis direction.
The title compound, C(5)H(8)ClNO(3), was prepared by the nucleophilic substitution reaction of (2S)-2-chloro-propanoyl chloride with glycine. The acetate group forms a dihedral angle of 84.6 (1)° with the mean plane of the C-NH-C=O fragment. In the crystal, the molecules are linked by N-H⋯O and O-H⋯O hydrogen bonds, generating a three-dimensional network,(More)
In the title compound, C27H21ClN2O4, the mean planes of the two indole ring systems (r.m.s. deviations = 0.021 and 0.024 Å) are approximately perpendicular to one another, with a dihedral angle of 79.54 (12)°. The benzene ring is twisted with respect to the mean planes of the two indole ring systems at angles of 80.14 (15) and 86.30 (15)°. In the crystal,(More)
The asymmetric unit of the title compound, C(16)H(17)FN(2)O(4)S, contains three independent mol-ecules, in which the pyrimidine and benzene rings are oriented at dihedral angles of 41.72 (3)°, 26.21 (3)° and 36.49 (3)°. Intra-molecular C-H⋯O hydrogen bonds result in the formation of two six- and one seven-membered non-planar rings, which have have twist(More)
In the title compound, C27H22N2O4, the two indole ring systems are approximately perpendicular to each other, with a dihedral angle of 84.5 (5)° between their planes; the benzene ring is twisted with respect to the two indole ring systems at angles of 78.5 (5) and 86.5 (3)°. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, weak C-H⋯O and C-H⋯N(More)
In the title compound, C27H21FN2O4, the mean planes of the two indole ring systems (r.m.s. deviations = 0.0166 and 0.0086 Å) are approximately perpendic-ular to one another, making a dihedral angle of 87.8 (5)°; the fluorobenzene ring is twisted with respect to the mean planes of the two indole ring systems at 82.7 (5) and 85.5 (3)°. In the crystal, pairs(More)
The title compound, C7H2ClF3O2, was prepared by the chlorination of 3-amino-2,4,5-trifluoro-benzoic acid. The carboxyl group is twisted relative to the benzene ring by 6.8 (1)°. In the crystal, pairs of O-H⋯O hydrogen bonds link mol-ecules into typical centrosymmetric carb-oxy-lic acid dimers. These dimers are arranged into sheets parallel to (-103).
