Crystal structure of (E)-2-(furan-2-ylmethylidene)-2,3,4,9-tetrahydro-1H-carbazol-1-one

Abstract

The title compound, C17H13NO2, crystallizes with two conformationally very similar independent molecules (A and B) in the asymmetric unit. In the crystal, the individual molecules are linked by pairs of N—H...O hydrogen bonds forming A–A and B–B inversion dimers, with R22(10) rings. They stack alternately up the a-axis direction and are linked by C—H...π interactions, forming sheets parallel to the ab plane.
