Abstract
The new compounds with the sum formulae [Cs([18]crown-6)](2)[Zn(C2H)(4)] . 8NH(3), Rb-3[Rb([18]crown-6)(NH3)][Cd(C2H)(4)](2) . {[18]crown-6 . 2NH(3)} . 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 ...
The new compounds with the sum formulae [Cs([18]crown-6)](2)[Zn(C2H)(4)] . 8NH(3), Rb-3[Rb([18]crown-6)(NH3)][Cd(C2H)(4)](2) . {[18]crown-6 . 2NH(3)} . 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 AC(2)H (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 C-2(2-) in liquid ammonia and again proves that acetylides slowly dissolve in this medium.
