【摘要】 2-甲基-4-(p-甲苯基)(a)和2-甲基-4-(p-氯苯基)(b)的-2,3-二氢-(1,5)苯并硫氮杂(艹卓)用X-射线单晶结构分析测定晶体结构,晶体结构由直接法解出.晶体(a)属于三斜空间群ci4—p1-,晶体胞参数:a=8.860(2),b=10.838(4),c=15.934(4),α=73.12(2),β=86.78(2),γ=79.96(2)°;z=4.对2743个衍射点进行修正,最终的一致性因子R=0.059.晶体(b)属于三斜空间群ci1-p1-,晶体参数:a=8.884(2),b=10.923(3),c=15.838(4);α=72.38(2),β=85.95(2),γ=79.93(2)°;z=4.对2109个衍射点进行修正,最终的一致性因子R=0.069.晶体(a)和(b)是同晶.在二氢化合物中,硫、氮七员杂环为稍有畸变的船式构型.

【Abstract】 Two crystal structures of 2-methyl-4(p-tolyl)(a) and 2-methyl-4-(p-chlorophenyl) (b)-2, 3-dihydro-(1,5) benzothiazepine have been determined by X-ray single-crystal structure analysis. Crystal structures were solved by direct method. Crystal(a) belongs to the triclinic space group Ci1-p1- with parameters a=8. 860(2), b=10.838(4), c=15.934(4); a=73.12(2), β=86.78(2), γ=79.96(2)°; Z=4. For 2743 reflections block-matrix refinement gave the final discrepancy R=0.059. Crys tal(b) belongs to the triclinic space group Ci1-p1- with parameters a= 8. 842(2), b=10.923, c=15.838(4); a=72.38(2),β=85.95(2), γ=79.93(2)°; Z=4. For 2109 reflections R=0. 069. Crystals(a) and (b) are isomophous. The conformation of seven member ring is slightly distorted boat form. Dihydro-compounds have a nonplanar conjugation system, in which there is a considerable twist around the singlebond -C6-N-. The dihedral angle between two benzene rings is 56.9°.
