Abstract
In the title compound, C27H21N3O6·C2H5OH, the indole ring systems are approximately perpendicular to each other, with a dihedral angle of 89.3 (5)°; the plane of the benzene ring is oriented with respect to the indole ring systems at 49.9 (5) and 73.4 (3)°. In the crystal, mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds and weak C-H⋯π inter-actions into a three-dimensional supra-molecular architecture. A void of 33.0 (7) Å(3) is observed in the crystal structure. The solvent ethanol molecule acts as a donor, forming an O-H⋯O hydrogen bond, reinforcing the framework structure.

Summary
Indole derivatives are found abundantly in a variety of natural plants and exhibit various physiological properties (Poter et al, 1977; Sundberg, 1996). Bis-indolymethane derivatives are found to be potentially bioactive compounds (Chang et al, 1999; Ge et al, 1999). The synthesis and application of bis-indolymethane derivatives have been widely studied. The title compound is one of the bis-indolymethane derivatives as a precursor for MRI contrast agents (Ni, 2008). We report the synthesis and crystal structure of the title compound
