X-ray single crystal diffraction at 100 K. The crystals of 1 are triclinic: space group P 1 ¯ , a = 8.1542(2), b = 11.0728(3), c = 11.2680(3) A, α = 116.557(3), β = 95.155(2), γ = 108.258(2)°, V = 831.97(4) A3, Z = 2, R = 0.0251 for 2429 reflections; the crystals of 2 are monoclinic: space group P21/c, a = 11.7428(2), b = 11.3518(2), c = 12.5886(2) A, β = 93.659(2)°, V = 1674.66(5) A3, Z = 4, R = 0.0269
摘要 合成了两种新的结构异构体——2,4-二甲基-5-[甲基(苯磺酰基)氨基]苯磺酰氯(1)和2,4-二甲基-3-[甲基(苯磺酰基)氨基]苯磺酰氯(2) N-(2,4-二甲基苯基)-N-甲基-苯磺酰胺或N-(2,6-二甲基苯基)-N-甲基苯磺酰胺与氯磺酸的相互作用。两种化合物均已通过 100 K 下的 X 射线单晶衍射进行结构表征。 1 的晶体为三斜晶系:空间群 P 1 ¯ , a = 8.1542(2), b = 11.0728(3), c = 11.2680(3) A, α = 116.557(3), β = 95.155(2), γ = 108.258(2)°, V = 831.97(4) A3, Z = 2, R = 0.0251 2429 次反射;2的晶体为单斜晶系:空间群P21/c, a = 11.7428(2), b = 11.3518(2), c = 12.5886(2) A
