Abstract

In the title compound, C29H25N3O6, the mean planes of the two indole ring systems (r.m.s. deviations = 0.0115 and 0.0082 Å) are approximately perpendic-ular to one another, making a dihedral angle of 89.7 (5)°; the benzene ring is twisted with respect to the two indole ring systems by 52.6 (4) and 88.2 (3)°. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules into the inversion dimers, which are further linked into supra-molecular chains along the b-axis direction. Weak C-H⋯O hydrogen bonds and C-H⋯π inter-actions are also observed in the crystal.

Summary

Chemical context

Bis(indolyl)methane derivatives are abundantly present in various terrestrial and marine natural resources (Porter et al., 1977; Sundberg, 1996). They are important antibiotics in the field of pharmaceuticals with diverse activities, such as anticancer, antileishmanial and antihyperlipidemic (Chang et al., 1999; Ge et al, 1999). We have reported the synthesis and crystal structures of some similar bis(indoly)methane compounds (Sun et al, 2012, 2015; Li et al, 2014; Lu et al, 2014). We report on the crystal structure of the title bis(indoly)methane compound
