Crystal structure and Hirshfeld surface analysis of 5-acetyl-3-amino-6-methyl-N-phenyl-4-[(E)-2-phenyl-ethen-yl]thieno[2,3-b]pyridine-2-carbox-amide.

ABSTRACT

The asymmetric unit of the title compound, C25H21N3O2S, comprises four mol-ecules. Their conformations differ primarily in the orientations of the styryl and the N-phenyl-carboxamido groups. In the crystal, inter-molecular N-H⋯N, C-H⋯O and C-H⋯S hydrogen-bonding contacts as well a C-H⋯π(ring) inter-actions lead to the formation of a layer structure parallel to (010). Hirshfeld surface analysis revealed that H⋯H inter-actions represent the main contributions to the crystal packing.
