In the title compounds, CHFNOS () and CHFNOS (), the benzo-thio-phene rings are essentially planar with maximum deviations of 0.009 (1) and 0.001 (1) Å for the carbon and sulfur atom in compounds and , respectively. In , the thio-phene ring system is almost orthogonal to the phenyl ring attached to the sulfonyl group, with a dihedral angle of 77.7 (1)°. In compound , the mol-ecular structure is stabilized by weak C-H⋯O intra-molecular inter-actions formed by the sulfone oxygen atoms, which generate two (5) ring motifs. In the crystal of , N-H⋯O hydrogen bonds link the mol-ecules into (8) rings, which are connected into a (10) chain C-H⋯F hydrogen bonds. Inter-molecular C-H⋯π inter-actions are also observed. In compound , the mol-ecules are linked C-H⋯O and C-H⋯F hydrogen bonding, generating infinite (11) and (13) chains running parallel to [010].
在标题化合物CHFNOS（）和CHFNOS（）中，苯并噻吩环基本呈平面状，化合物中碳和硫原子的最大偏差分别为0.009（1）Å和0.001（1）Å。在中，噻吩环系统与连接到磺酰基的苯环几乎正交，二面角为77.7（1）°。在化合物中，分子结构通过由砜氧原子形成的弱C-H⋯O分子内相互作用得以稳定，这产生了两个（5）环基序。在的晶体中，N-H⋯O氢键将分子连接成（8）环，这些环通过C-H⋯F氢键连接成一个（10）链。还观察到分子间C-H⋯π相互作用。在化合物中，分子通过C-H⋯O和C-H⋯F氢键相连，形成平行于[010]的无限（11）和（13）链。
