The X-ray crystallographic structures of 2-(2-phenyl-5-oxo-1,3,2-oxathiagermolan-2-ylthio)acetic acid (2), its pyridinium salt (3), and the pyridinium salt of 2-(2-t-butyl-5-oxo-1,3,2-oxathiagermolan-2-ylthio)acetic acid (1), (4), together with 2-(2-phenyl-1,3,2-oxathiagermolan-2-ylthio)ethanol (5) were determined and compared with that of 1. All of compounds investigated, 2–5, have the TBP-like, pentacoordinated
2-(2-苯基-5-氧代-1,3,2-氧杂噻喃-2-基硫基)乙酸(2),其吡啶鎓盐(3)和2-吡啶鎓盐的X射线晶体结构(2-叔丁基-5-氧代-1,3,2-氧杂噻喃-2-基硫基)乙酸(1),(4),以及2-(2-苯基-1,3,2-氧杂噻吩喃-确定了2-ylthio)ethanol(5)并与1进行了比较。所有化合物的研究,2 – 5,具有类似TBP的五坐标结构。这一事实似乎表明,这类化合物的五配位反应的驱动力是存在相对于锗原子的氧原子δ,该氧原子通过超配位容易形成五元环。
