C_(17)H_(17)N_2O_2Cl_2PS(NP-8)和C_(17)H_(19)N_2O_2PS(NP-10-II)两个晶体结构是用帕特逊法测定的,它们均属单斜晶系,空间群分别为P2_1/a和P2_1/n.单胞中有四个分子.晶胞参数分别为:a=26.622(7)A,b=7.711(2)A,c=9.461(3)A,β=94.90°(4);a=18.897(3)A,b=10.199(13)A,c=8.948(3)A,β=94.30°(3).经块对角矩阵最小二乘法修正,对NP-8晶体的全部2971个衍射点,偏离因子R=0.046;对NP-10-II 晶体的 1711(I)>3σ(I)衍射点,偏离因子 R=0.076. 文中根据NP-8和 NP-10-II的分子结构,合理地解释了光谱数据,并对结构特点进行了讨论。
Two crystal structures of C_ (17) H_ (17) N_2O_2Cl_2PS (NP-8) and C_ (17) H_ (19) N_2O_2PS (NP-10-II) were measured by the method of Paterson, The space group is P2_1 / a and P2_1 / n, respectively, and there are four elements in the unit cell.The unit cell parameters are as follows: a = 26.622 (7) A, b = 7.711 (2) A, c = 9.461 (3) A, β = 94.90 ° (4); a = 18.897 (3) A, b = 10.199 (13) A, c = 8.948 (3) A, β = 94.30 ° The correction factor is R = 0.046 for all the 2971 diffraction points of NP-8 crystal and the deviation factor R = 0.076 for 1711 (I)> 3σ (I) diffraction point of NP-10- 8 and NP-10-II molecular structure, a reasonable explanation of the spectral data, and the structural characteristics are discussed.
