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−.
