N'-[(E)-4-(Dimethyl-amino)-benz-ylidene]-2-(5-meth-oxy-2-methyl-1H-indol-3-yl)acetohydrazide.

ABSTRACT: In the title compound, C(21)H(24)N(4)O(2), inversion-related mol-ecules are linked into dimers through pairs of N-H⋯O hydrogen bonds, which generate R(2) (2)(8) motifs. As well as dimer formation, an additional N-H⋯O hydrogen bond and two C-H⋯π contacts, involving H atoms from the phenyl ring and the pyrrole and benzene rings of the indole system, generate a three-dimensional network.

N'-[(E)-4-Meth-oxy-benzyl-idene]-2-(5-meth-oxy-2-methyl-1H-indol-3-yl)acetohydrazide.

Project description:The conformation adopted by the title compound, C20H21N3O3, in the crystal is 'J'-shaped and appears to be at least partially directed by a weak intra-molecular C-H?N hydrogen bond. In the crystal, mol-ecules are linked by N-H?O hydrogen bonds, forming dimers with R 2 (2)(8) motifs. Furthermore, these dimers connect to each other via C-H?O and N-H?O hydrogen bonds to form a three-dimensional network.

Ethyl 2-(5-meth-oxy-2-methyl-1H-indol-3-yl)acetate.

Project description:In the title compound, C14H17NO3, the nine-membered 1H-indole ring system is essentially planar [maximum deviation = 0.019 (1) Å]. In the crystal, mol-ecules are linked via N-H⋯O hydrogen bonds, forming chains along [001]. These chains are linked via C-H⋯O hydrogen bonds and C-H⋯π inter-actions, forming a two-dimensional network lying parallel to the ac plane.

5-Meth-oxy-2-[(5-meth-oxy-1H-indol-1-yl)carbon-yl]-1H-indole.

Project description:The asymmetric unit of the title compound, C(19)H(16)N(2)O(3), comprises three independent mol-ecules (A, B and C). The inversion-related molecule of A is virtually superimposable upon the other two molecules. In each mol-ecule, there is a twist in the link between the approximately syn carbonyl and amine groups [the N-C-C-O torsion angles range from 19.73?(19) to -21.2?(2)°]. Each mol-ecule has a bent shape quanti-fied in terms of the dihedral angle between the indole and indole fused-ring systems [range = 45.69?(5)-47.91?(5)°]. In the crystal, the A and B mol-ecules form dimeric aggregates via ten-membered {?HNC(2)O}(2) synthons, while the C mol-ecules self-associate similarly but about a centre of inversion.

5-Meth-oxy-3-[(5-meth-oxy-1H-indol-3-yl)(phen-yl)meth-yl]-1H-indole.

Project description:In the title compound, C(25)H(22)N(2)O(2), the indole rings are individually almost planar [with maximum deviations of 0.0116 (19) and 0.0113 (18) Å] and are almost orthogonal to each other, making a dihedral angle of 84.49 (6)°. The benzene ring is inclined at 72.83 (9) and 80.85 (9)° with respect to the indole rings. In the crystal, mol-ecules are linked by N-H⋯O inter-actions into chains running parallel to the c axis. The crystal structure is further stabilized by C-H⋯π inter-actions.

Project description:In the title compound, C(24)H(25)NO(7)S, the sulfonyl-bound phenyl ring is approximately perpendicular to the indole ring system [dihedral angle = 87.72?(5)°].

In the crystal structure, mol-ecules are linked into a ribbon structure running along the c axis by inter-molecular C-H?O hydrogen bonds and C-H?? inter-actions involving the pyrrole ring.
