The mol-ecule 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 thio-phene rings. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, two adjacent mol-ecules are linked into a dimer in an anti-parallel face-to-face manner by a pair of C-H⋯O inter-actions. Neighboring dimers are further linked into chains along the c-axis direction by N-H⋯N hydrogen bonds.
标题杂芳基查尔酮衍生物C₁₃H₁₁NOS的分子呈反式构型，几乎是平面的，苯环和噻吩环之间的二面角为3.73 (8)°。分子内N-H⋯O氢键形成一个S(6)环 motif。在晶体中，两个相邻分子通过一对C-H⋯O相互作用以反平行面对面的方式连接成二聚体。相邻的二聚体通过N-H⋯N氢键沿c轴方向进一步连接成链。
