Reconfirmation of Solubility of C22− in Liquid Ammonia: Syntheses and Crystal Structures of the Tetrahedral Acetylide Ammoniates [Zn(C2H)4]2−, [Cd(C2H)4]2− and [In(C6H5)3(C2H)] −

The new compounds with the sum formulae [Cs([18]crown-6)]2[Zn(C2H)4] ⋅ 8NH3, Rb3[Rb([18]crown-6)(NH3)][Cd(C2H)4]2 ⋅ {[18]crown-6 ⋅ 2NH3} ⋅ NH3 and [Cs([2.2.2]crypt)][In(C6H5)3(C2H)] were synthesized in liquid ammonia. The anionic units show tetrahedrally coordinated central atoms with four hydrogenacetylide ligands or one C2H− and three C6H5− ligands. Solid state starting materials for these ligands were either AC2H (A=Rb, Cs) or Cs2C2. The fact that the indium compound contains a hydrogenacetylide ligand, which was formed from Cs2C2, confirms again the equilibrium of the species C2H2, C2H− and C22− in liquid ammonia and again proves that acetylides slowly dissolve in this medium.

重新确认 C22- 在液氨中的溶解度：四面体乙炔化物 [Zn(C2H)4]2-、[Cd(C2H)4]2- 和 [In(C6H5)3(C2H)]-的合成和晶体结构
新化合物的总和式为 [Cs([18]crown-6)] 2 [Zn(C 2 H) 4 ] ⋅ 8NH 3 , Rb 3 [Rb([18]crown-6)(NH 3 )][ Cd(C 2 H) 4 ] 2 ⋅ {[18]crown-6 ⋅ 2NH 3 } ⋅ NH 3和 [Cs([2.2.2]crypt)][In(C 6 H 5 ) 3 (C 2 H) ] 在液氨中合成。阴离子单元显示四面体配位的中心原子与四个乙炔氢配体或一个 C 2 H -和三个 C 6 H 5 -配体。这些配体的固态起始材料是A C 2 H（A = Rb，Cs）或Cs 2 C 2。铟化合物含有由 Cs 2 C 2形成的氢乙炔配体这一事实再次证实了 C 2 H 2、C 2 H -和 C 2 2-在液氨中的平衡，并再次证明乙炔缓慢溶解在这种介质中。
