Abstract Beryllium metal was dissolved in liquid ammonia at ambient temperature through addition of alkali metals. Thereby, the amidoberyllates Cs[Be(NH2)3], [Na4 (NH2)2][Be(NH2)4] and K4[Be2O(NH2)4][Be(NH2)3]2 were isolated and structurally characterized via single crystal X-ray diffraction. In the case of Li we were able to synthesize Be(NH2)2 at ambient temperature. We present the first example of a [Be(NH2)4]2− anion as well as the first oxyamidoberyllate anion [Be2O(NH2)4]2−.

铍和碱金属在液氨中形成酰胺基铍酸盐

摘要 通过添加碱金属,在常温下将金属铍溶解在液氨中。因此,酰胺基铍酸盐 Cs[Be(NH2)3]、[Na4 (NH2)2][Be(NH2)4] 和 K4[Be2O(NH2)4][Be(NH2)3]2 通过单晶 X 射线衍射。在 Li 的情况下,我们能够在环境温度下合成 Be(NH2)2。我们展示了第一个 [Be(NH2)4]2- 阴离子以及第一个氧酰氨基铍阴离子 [Be2O(NH2)4]2- 的例子。
