Schisandrone的晶体结构测定
Determination of Crystal Structure of Schisandrone
【摘要】 Schisandrone,C21H24O5,是无色针状结晶,属三斜晶系,晶胞参数:a=9.109(3),b=9.749(2),c=11.663;α=65.21(1),β=89.82(1),γ=89.96(2)(°),Z=2.结构解析计算采用MULTAN 82直接法程序,精修后的偏离因子R=0.060,结果表明,该化合物是一个具有4-苯代四氢萘骨架的木脂素。
【Abstract】 The needle crystal of Schisandrone, C21H24O5, which is colorless and transparent, belongs to triclinic system. The unit cell parameters are a=9. 109(3) , 6 = 9. 749(2) , c= 11. 663(1) A ; α = 65.21(1), β=89. 82(1), γ=89. 96(2)(°); Z=2.In all the calculations of structure analysis, Direct Method programme of MULT AN 82 was used. All of the atomic coordinates and thermal parameters have been refined to R=0. 060 for 3521 reflections having I>3. Oσ(I). The diffractometry result shows that Schisandrone is a 4-aryltetralone lig-nan, which is the same as the result of spectroscopic determination.
