Carbides with Main Group and 5f Elements

Synthesis and characterization of binary and ternary carbides with main group elements like sulfur, selenium and tellurium.

We have investigated the reactivity of alkali metal acetylides AIC2H and AI2C2 with group 16 elements (S, Se, Te) in liquid ammonia. Using grey selenium as one of the starting materials we obtained new compounds with the general formula AISeC2H (AI = K, Rb, Cs). Possible compounds with the composition A2Se2(C2) (AI = K, Rb, Cs) are likely to exist. In this context our still preliminary results on similar reactions of sulfur and tellurium with AIC2H in liquid ammonia are notable.
