By reaction of GeI4, [N(nBu)4]I as iodide donor, and [NMe(nBu)3][N(Tf)2] as ionic liquid, reddish-black, plate-like shaped crystals are obtained. X-ray diffraction analysis of single crystals resulted in the compositions ;alpha;-[NMe(nBu)3](GeI4)I (Pbca; a = 1495.4(3) pm; b = 1940.6(4) pm; c = 3643.2(7) pm; Z = 16) and β-[NMe(nBu)3](GeI4)I (Pn; a = 1141.5(2) pm; b = 953.6(2) pm; c = 1208.9(2) pm; β
通过GeI4与作为碘化物供体的[N(nBu)4]I和作为离子液体的[NMe(nBu)3][N(Tf)2]反应,得到红黑色片状晶体。单晶的 X 射线衍射分析得出的组成为 ;α;-[NMe(nBu)3](GeI4)I (Pbca; a = 1495.4(3) pm; b = 1940.6(4) pm; c = 3643.2( 7) pm; Z = 16) 和 β-[NMe(nBu)3](GeI4)I (Pn; a = 1141.5(2) pm; b = 953.6(2) pm; c = 1208.9(2) pm; β = 100.8(1)°;Z = 2)。取决于反应温度,选择性地形成一种或其他化合物。此外,GeI4 和 [N(nBu)4]I 的反应,使用 [ImMe(nBu)][BF4] (Im = 咪唑) 作为离子液体,导致 [ImMe(nBu)][N( nBu)4](GeI4)3I2 (P21/c;
