RESUMO
In the title compound, C(25)H(23)BrN(2)O(4), the seven-membered ring adopts a twisted-boat conformation. The indole ring system is planar within 0.021â (2)â Å and the ester group [-C(=O)-O-C-] is almost coplanar with it [dihedral angle = 3.0â (2)°]. The conformation of the ester group is influenced by intra-molecular C-Hâ¯O inter-actions. In the crystal structure, mol-ecules are linked into chains along the b axis by C-Hâ¯N hydrogen bonds.
RESUMO
In the title compound, C26H25NO6S, the S atom shows a distorted tetra-hedral geometry, with O-S-O [119.46â (9)°] and N-S-C [107.16â (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 41.1â (1) and 83.3â (1)°, respectively, with the formyl-phenyl and phenyl rings. The dihedral angle between formyl-phenyl and phenyl rings is 47.6â (1)°. The crystal packing features C-Hâ¯O hydrogen-bond inter-actions.
