The title compounds, C(20)H(25)N(2)O(2)S(+).I(-), (I), and C(29)H(25)BrN(2)O(2)S, (II), respectively, both crystallize in space group P-1. The pyrrole ring subtends an angle with the sulfonyl group of 33.6 degrees in (I) and 21.5 degrees in (II). The phenyl ring of the sulfonyl substituent makes a dihedral angle with the best plane of the indole moiety of 81.6 degrees in (I) and 67.2 degrees in (II)
标题化合物C(20)H(25)N(2)O(2)S(+)。I(-),(I)和C(29)H(25)BrN(2)O(2 S,(II)分别在空间群P-1中结晶。吡咯环与(I)中的磺酰基对角为33.6度,(II)中为21.5度。磺酰基取代基的苯环与吲哚部分的最佳平面在(I)中为81.6度,在(II)中为67.2度形成二面角。两种化合物中CN键距离的延长或缩短是由于苯磺酰基的吸电子特性。S原子为扭曲的四面体构型。(I)中的CH.O和CH.I相互作用以及(II)中的CH.O和CH.N相互作用稳定了分子结构。
