Abstract

High-resolution solid-state magic angle spinning 73Ge NMR spectra of hexavalent germanium compounds, i.e. diiodogermylene (1a) and bis(1-pyrrolyl)(meso-tetraphenylporphyrinato)germanium (3a), were determined. To the best of our knowledge, this is the first example of high-resolution solid-state 73Ge NMR spectra of hexacoordinated germanium nuclei. The symmetry requirement for observation of high-resolution solid-state 73Ge NMR spectra is discussed.

摘要

测定了六价锗化合物二碘锗烯（1a）和双（1-吡咯基）（中-四苯基卟啉基）锗（3a）的高分辨率固态魔角旋转73Ge核磁共振谱。据我们所知，这是六配位锗核的高分辨率固态73Ge核磁共振谱的首个实例。讨论了观测高分辨率固态73Ge核磁共振谱的对称性要求。
