The indole and indane moieties of the title molecule, C 18 H 13 NO, form a dihedral angle of 10.2 (2) . In the crystal structure, symmetry-related molecules are linked by intermolecular NÐHÁ Á ÁO and CÐHÁ Á ÁO hydrogen bonds to form in®nite one-dimensional chains along the b axis. This chain structu
The crystal structure of the title compound, C~14~H~12~N~2~O~2~, is stabilized by intermolecular N—H...O and C—H...N hydrogen bonds and also by C—H...π and π–π [centroid–centroid distance 3.822 (1) Å and a plane-to-plane separation 3.697 Å] interactions. The N—H...O and C—H...N hydrogen bonds genera
