In the title compound, C(13)H(11)NOS·0.5C(2)H(6)O, the chalcone derivative is close to planar, the dihedral angle between the thio-phene and 4-amino-phenyl rings being 3.1 (2)°. The thio-phene ring is disordered over two orientations with occupancies of 0.842 (3) and 0.158 (3). In the crystal structure, mol-ecules are linked into chains along the b axis by N-H⋯O hydrogen bonds. The chains are crosslinked via N-H⋯π inter-actions involving the thio-phene ring. The ethanol solvent mol-ecule is also disordered over two positions, each with an occupancy of 0.25.
在标题化合物C(13)H(11)NOS·0.5C(2)H(6)O中，查尔酮衍生物接近平面结构，噻吩环与4-氨基苯环之间的二面角为3.1(2)°。噻吩环在两个取向之间无序，占有率分别为0.842(3)和0.158(3)。在晶体结构中，分子通过N-H⋯O氢键沿b轴连接成链。这些链通过涉及噻吩环的N-H⋯π相互作用交联。乙醇溶剂分子也在两个位置无序，每个位置的占有率为0.25。
