The molecular structure of N(GeH3)(PF2)2 in the gas phase has been determined by electron diffraction. The NGeP2 skeleton is planar, and the Ge–N bond is substantially longer than those found in N(GeH3)3. Principal geometric parameters (ra) are: r(P–F) 159.2(5), r(P–N) 169.8(8), and r(Ge–N) 188.9(13) pm; angle FPF 96.5(11), FPN 99.6(5), and PNP 114.0(8)°. The conformation adopted by the PF2 groups
N(GeH 3)(PF 2)2在气相中的分子结构已经通过电子衍射确定。NGeP 2骨架是平面的,并且Ge–N键比N(GeH 3)3中的键长得多。主要几何参数(r a)为:r(PF)159.2(5),r(PN)169.8(8)和r(Ge-N)188.9(13)pm;FPF 96.5(11),FPN 99.6(5)和PNP 114.0(8)°。PF 2采用的构型基团是其中氮和磷孤对的轴几乎正交,而两个磷原子的轴在骨架平面上彼此近似顺式排列的基团。
