1.化合物 最典型的 结构特征 是 通过sp3杂化碳 为中心 连接 两个 笏刚性平面,由于 刚性骨架的 作用,以sp3杂化碳为中心 的 四面体 与 理想四面体结构 有一定的偏差。
The most typical structural characteristic of compound is connect two scepter rigid planes via sp3 hybridized carbon as center.Due to the rigid backbone effect, sp3 hybridized carbon centered tetrahedron is different from the ideal tetrahedron in terms of structure in some degree
2. 化合物中 sp3杂化碳中心 的六个角的 角度范围为105-110°。化合物的 两个芴环之间的二面角是IPASBF(89.3°),接近90°。
Regarding the structure of a compound, the six sp3 hybridized carbon centered angles are all within the range of 105-110°. The dihedral angle between two fluorene rings is IPASBF(89.3°), which is close to 90°
3. 化合物的 氮杂 笏刚性平面的平面性都比较好(平面的平均偏差在0.010-0.025A之间)。
The flatness of aza-scepter rigid planes of compound are both good (mean variation varys between 0.010-0.025A ) |
