Abstract

In the title compound, CHClNOS, the thio-phene ring is disordered in a 0.762 (3):0.238 (3) ratio by an approximate 180° rotation of the ring around the S-C bond linking the ring to the sulfonyl unit. The di-chloro-benzene group is also disordered over two sets of sites with the same occupancy ratio. The mol-ecular conformation is stabilized by intra-molecular C-H⋯Cl and C-H⋯N hydrogen bonds, forming rings with graph-set notation (5). In the crystal, pairs of mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds, forming inversion dimers with graph-set notation (8) and (11), which are connected by C-H⋯O hydrogen-bonding inter-actions into ribbons parallel to (100). The ribbons are further connected into a three-dimensional network by C-H⋯π inter-actions and π-π stacking inter-actions between benzene and thio-phene rings, with centroid-to-centroid distances of 3.865 (2), 3.867 (7) and 3.853 (2) Å. Hirshfeld surface analysis has been used to confirm and qu-antify the supra-molecular inter-actions.

摘要

在标题化合物CHClNOS中,噻吩环通过围绕将环与磺酰基单元相连的S-C键进行约180°的环旋转,以0.762 (3):0.238 (3)的比例无序排列。二氯苯基团也在两组占有率相同的位置上无序排列。分子构象通过分子内C-H⋯Cl和C-H⋯N氢键得以稳定,形成具有图式(5)的环。在晶体中,分子对通过N-H⋯O和C-H⋯O氢键相连,形成具有图式(8)和(11)的反演二聚体,这些二聚体通过C-H⋯O氢键相互作用连接成平行于(100)的带状结构。这些带状结构通过苯环和噻吩环之间的C-H⋯π相互作用和π-π堆积相互作用进一步连接成三维网络,质心间距为3.865 (2)、3.867 (7)和3.853 (2) Å。 Hirshfeld表面分析已用于确认和量化超分子相互作用。
