Abstract
The title compounds, C(27)H(26)Cl(2)NO(5)PS, (I), and C(27)H(27)BrNO(5)PS, (II), respectively, crystallize in the centrosymmetric space group P2(1)/n with one molecule in the asymmetric unit in each case. The dihedral angle between the benzene and pyrrole rings is 2.1 (1) degrees in (I) and 0.9 (2) degrees in (II). The phenylsulfonyl group is orthogonal to the halophenyl moiety, with a dihedral angle of 82.0 (1) degrees in (I) and 78.7 (2) degrees in (II). In both compounds, the molecular structures and packing are stabilized by C-H...O and C-H...halogen interactions. The intermolecular hydrogen bonds in (I) form cyclic dimers with graph-set descriptors R(2)(1)(10) and R(2)(2)(8) about a 2(1) axis, and those in (II) form a C(2)(2)(20) chain.
