Abstract

In the title compound, C(24)H(28)N(2)O(4)S(2), the dihedral angles between the central benzene ring and the pendant rings are 77.44 (11) and 79.23 (10)°, and the dihedral angle between the pendant rings is 23.31 (12)°. Both sulfonamide groups project to the same side of the central benzene ring and the mol-ecule has approximate non-crystallographic mirror symmetry. One of the ethyl side chains is disordered over two sets of sites in a 0.526 (14):0.474 (14) ratio. In the crystal, inversion dimers linked by pairs of weak C-H⋯O inter-actions occur, generating R(2) (2)(28) loops.

摘要

在标题化合物C₂₄H₂₈N₂O₄S₂中，中心苯环与侧环之间的二面角分别为77.44 (11)°和79.23 (10)°，侧环之间的二面角为23.31 (12)°。两个磺酰胺基团都伸向中心苯环的同一侧，分子具有近似的非晶体学镜面对称性。其中一个乙基侧链在两组位置上无序，比例为0.526 (14):0.474 (14)。在晶体中，通过成对的弱C-H⋯O相互作用形成反演二聚体，产生R₂²(28)环。
