(4-Bromo-phen-yl)(1H-indol-7-yl)methanone.

Project description:In the crystal, the mol-ecules of the title compound, C(15)H(10)BrNO, are connected into centrosymmetric dimers by pairs of N-H?O hydrogen bonds. The dihedral angle between the planes of indole ring system and benzene ring is 50.13?(5)°. The indole plane is significantly less twisted from the plane of the central C-C(=O)-C bridge than the benzene plane [dihedral angles = 15.51?(3) and 40.13?(7)°, respectively]. The bond angles within the benzene ring show an approximately additive effect of the influence of both substituents.

(2Z)-N-(2-Chloro-benz-yl)-2-(2-oxo-2,3-dihydro-1H-indol-3-yl-idene)hydrazinecarbothio-amide.

Project description:In the title compound, C(16)H(13)ClN(4)OS, the isatin ring system is oriented at dihedral angles of 10.60?(7) and 72.60?(3)° with respect to the thio-semicarbazide and 2-chloro-benzyl groups, respectively. The near planarity of the isatin and thio-semicarbazide groups [r.m.s. deviations of 0.0420 and 0.0163?Å, respectively] is reinforced by intra-molecular N-H?O and N-H?N hydrogen bonds, which generate S(6) and S(5) rings, respectively. In the crystal, inversion dimers linked by pairs of N-H?O hydrogen bonds generate R(2) (2)(8) loops. Aromatic ?-? stacking inter-actions between the centroids of heterocyclic five-membered and benzene rings [distance = 3.6866?(11)?Å] are also observed.

Project description:In the title compound, C(16)H(15)N(2) (+)·C(6)H(4)BrO(3)S(-), the cation exists in the E configuration and is essentially planar with a dihedral angle of 3.10?(5)° between the pyridinium ring and the indole ring system.

Project description:In the title compound, C(28)H(27)NO(6)S·0.5CHCl(3), the ethyl acrylate substituent adopts an extented conformation with all torsion angles close to 180°. The chloro-form solvent mol-ecule is disordered across an inversion centre and is therefore half occupied. The mol-ecular packing is controlled by inter-molecular C-H?O inter-actions.
