(E)-1-(2-Aminophenyl)-3-(thiophen-2-yl)prop-2-en-1-one

Abstract

The molecule of the title heteroaryl chalcone derivative, C13H11NOS, exists in a trans-configuaration and is almost planar with a dihedral angle of 3.73 (8)° between the phenyl and thiophene rings. An intramolecular N—H...O hydrogen bond generates an S(6) ring motif. In the crystal, two adjacent molecules are linked into a dimer in an anti-parallel face-to-face manner by a pair of C—H...O interactions. Neighboring dimers are further linked into chains along the c-axis direction by N—H...N hydrogen bonds.
