Hirshfeld Analysis

In the title compound, C26H22N2O2, the dihedral angles between the 1-methylindole units (A and B) and the benzoic acid moiety (C) are A/B = 64.87 (7), A/C = 80.92 (8) and B/C = 75.05 (8)°. An intramolecular C—H...O interaction arising from the methyne group helps to establish the conformation. In the crystal, R 2 2(8) carboxylic acid inversion dimers linked by pairs of O—H...O hydrogen bonds are observed. A Hirshfeld surface analysis shows that the greatest contributions are from H...H, C...H/H...C and O...H/H...O contacts (percentage values = 54.6%, 29.6% and 10.1%, respectively).
