Abstract
In the title compound, C(6)H(4)Cl(2)OS, the acetyl group is almost coplanar with the thio-phene ring [dihedral angle = 4.01 (2)°]. In the crystal, short inter-molecular O⋯Cl contacts [2.9494 (14) and 3.1191 (14) Å] link the mol-ecules into infinite (100) sheets and aromatic π-π stacking [centroid-centroid separation = 3.5422 (10) Å] consolidates the packing.
摘要
在标题化合物C(6)H(4)Cl(2)OS中，乙酰基与噻吩环几乎共面[二面角 = 4.01 (2)°]。在晶体中，短的分子间O⋯Cl接触[2.9494 (14) 和3.1191 (14) Å]将分子连接成无限的(100)层，芳香π-π堆积[质心-质心间距 = 3.5422 (10) Å]巩固了堆积。
