Abstract

Three alkali metal acetylides, namely KNaC2, KRbC2, and NaRbC2, were synthesized and characterized by means of X-ray powder diffraction. KNaC2 and KRbC2 crystallize as a variant of the anti-PbCl2-type structure (Pnma, Z = 4), whereas NaRbC2 crystallizes as a variant of the anti-PbFCl-type structure (Pmmn, Z = 2). Based on a simple systematic approach developed by Sabrowsky et al. for inter-alkali metal chalcogenides all known inter-alkali metal acetylides can be classified into two classes: variants of the anti-PbCl2 type structure and variants of the anti-PbFCl type structure. Acetylides with Q(ABC(2)) 1.45 crystallize in the anti-PbCl2-type structure, whereas for Q(ABC(2)) > 1.45 the anti-PbFCl-type structure is found (Q(ABC(2)) = V-m(A(2)C(2))/V-m(B2C2) with V-m(A(2)C(2)) > V-m(B2C2); V-m: molar volume, A, B = alkali metals).
