[Yb(NH3)8][Yb(PYr)6]：电子诱导液氨合成与结晶
金属Yb与吡咯(C4H4NH)在35℃的液氨中反应生成单晶黄色[Yb(NH3)8][Yb(Pyr)6](Pyr−=吡咯酸盐阴离子，C4H4N−)。在−35℃下，过量的氨水和过量的吡咯共同阻止了分子化合物[Yb(PYR)3(PYRH)2(NH3)2]的形成。[Yb(NH3)8][Yb(PYR)6]由两个均一的离子单元组成，如果从氨气气氛中除去，就会迅速分解，即。它显示氨蒸气压力>；1巴。
[Yb(NH3)8][Yb(Pyr)6]: Electride Induced Synthesis and Crystallization from Liquid Ammonia
Single crystalline yellow [Yb(NH3)8][Yb(Pyr)6] (Pyr− = pyrrolate anion, C4H4N−) was obtained by the reaction of ytterbium metal with pyrrole (C4H4NH) in liquid ammonia at −35 °C. Significant excess of ammonia together with avoiding a pyrrole excess prevents formation of the molecular compound [Yb(Pyr)3(PyrH)2(NH3)2]. [Yb(NH3)8][Yb(Pyr)6] consists of two homoleptic ionic units and rapidly decomposes if removed from the ammonia atmosphere, viz. it shows an ammonia vapour pressure >1 bar.
