摘要
本文获得了标题季铵盐的~1H、^(13)C、^(11)B、^(13)C-~1H多核和二维异核相关波谱,并作了归属,还弄清了^(13)C和~1H核间相干传递关系。探寻了[B_3H_8]^-的波谱特性及其原因。从X射线单晶衍射法获得的键长、键角、二面角、配位数等数据和晶胞中分子的空间排列图,确定出分子的空间结构。
The organic group contained in the objective compound of quaternary ammonium salt isdatermined by FT-IR spectroscopy. Also ~1H, ^(13)C, ^(11)B, ^(13)C-~1H multinuclear and 2D heteronuclearcorrelated spectroscopy is obtained. For δ_H, δ_C, δ_B, they are belonged to, and due to two di-mension heteronuclear shift correlated spectroscopy we have understand fully the relation of correlatedtransmision between ^(13)C and ~1H nuclei. The molecular structure is determined. The NMR spec-troscopy speciality of (B_3H_8)^- is inquired. Not only the data on bond lengh, bond angle, two-faceangle, ligand number, and so on, but also the specra of molecular space arrange in crystal cellare acquired by X-ray single crystal diffraction, thus the molecular space structure is defined.
