Three alkali metal acetylides, namely KNaC2, KRbC2, and NaRbC2, were synthesized and characterized by means of X‐ray powder diffraction. KNaC2and KRbC2crystallize as a variant of theanti‐PbCl2‐type structure (Pnma,Z= 4), whereas NaRbC2crystallizes as a variant of theanti‐PbFCl‐type structure (Pmmn,Z= 2). Based on a simple systematic approach developed bySabrowskyet al. for inter‐alkali metal chalcogenides all known inter‐alkali metal acetylides can be classified into two classes: variants of theanti‐PbCl2type structure and variants of theanti‐PbFCl type structure. Acetylides withQ(ABC2) ≤ 1.45 crystallize in theanti‐PbCl2‐type structure, whereas forQ(ABC2) > 1.45 theanti‐PbFCl‐type structure is found (Q(ABC2) =Vm(A2C2)/Vm(B2C2) withVm(A2C2) >Vm(B2C2);Vm: molar volume,A,B= alkali metals).
