چکیده
There are two independent mol-ecules (A and B) in the asymmetric unit of the title compound C11H10BrClO2, which represents the Z isomer. The methyl-acrylate moieties are essentially planar, within 0.084 (2) and 0.027 (5) Å in mol-ecules A and B, respectively. The benzene ring makes dihedral angles of 13.17 (7) and 27.89 (9)° with the methyl-acrylate moiety in mol-ecules A and B, respectively. The methyl-bromide moiety is almost orthogonal to the benzene ring, making dihedral angles of 81.46 (16)° in mol-ecule A and 79.61 (16)° in mol-ecule B. The methyl-acrylate moiety exhibits an extended trans conformation in both mol-ecules. In the crystal, pairs of C-H⋯O hydrogen bonds result in the formation of quasi-centrosymmetric R 2 (2)(14) AB dimers.

In the title indole derivative, C20H18ClNO2, the chloro-phenyl ring is almost perpendicular to the indole moiety, making a dihedral angle of 87.6 (1)°. The mol-ecular packing is stabilized by C-H⋯π inter-actions, which form a C(9) chain motif along [10-1]. In addition, there are weak π-π inter-actions [centroid-centroid distance 3.851 (1) Å] between the chains, involving inversion-related chlor...

In the title compound, C26H25NO6S, the S atom shows a distorted tetra-hedral geometry, with O-S-O [119.46 (9)°] and N-S-C [107.16 (7)°] angles deviating from ideal tetra-hedral values, a fact attributed to the Thorpe-Ingold effect. The sulfonyl-bound phenyl ring forms dihedral angles of 41.1 (1) and 83.3 (1)°, respectively, with the formyl-phenyl and phenyl rings. The dihedral angle between for...
