The synthesis of ternary acetylides Li₂TeC₂ and Na₂TeC₂ is presented as the first example of ternary acetylides with metalloid elements instead of transition metals. The synthesis was carried out by the direct reaction of the corresponding bialkali acetylides with tellurium powder in liquid ammonia. Alternatively, the synthesis of Na₂TeC₂ was also carried out by the direct reaction of tellurium powder and two equivalents of NaC₂H in liquid ammonia leading to Na₂TeC₂ and acetylene gas through an equilibrium containing the assumed NaTeC₂H molecules besides the reactants and the products. The resulting disordered crystalline materials were characterized by X-ray diffraction and Raman spectroscopy. Implications of these new syntheses on the synthesis of other ternary acetylides with metalloid elements and transition metals are also discussed.
