The title compound, C10H9FN4S, crystallizes with two mol-ecules (A and B) in the asymmetric unit. The dihedral angle between the planes of the trizole and fluoro-benzene rings is 7.3 (3)° in mol-ecule A and 41.1 (3)° in mol-ecule B. Mol-ecule A features an intra-molecular C-H⋯S hydrogen bond, which closes an S(6) ring. In the crystal, A+B dimers linked by pairs of N-H⋯S hydrogen bonds occur, generating R 2 (2)(8) loops. Weak π-π stacking contacts [centroid-centroid separation = 3.739 (6) Å] are also observed.
标题化合物C₁₀H₉FN₄S在不对称单元中含有两个分子(A和B)。三唑环和氟苯环平面之间的二面角在分子A中为7.3(3)°,在分子B中为41.1(3)°。分子A具有分子内C-H⋯S氢键,形成一个S(6)环。在晶体中,通过N-H⋯S氢键对连接的A+B二聚体形成,产生R ₂(2)(8)环。还观察到弱的π-π堆积接触[质心-质心间距 = 3.739(6)Å]。
