合成了三种新的碱金属乙酰基化合物CsNaC2、CsKC2和CsRbC2，并用同步加速器粉末衍射对其进行了表征。作为一种新的合成方法，二元碱金属乙酰醚在相对较低的温度下（200℃）进行了反应。DSC测量证明了该反应的普遍可用性。CsKC2和CsRbC2结晶为一种抗pbcl2型结构（Pnma, Z = 4），而CsNaC2结晶为一种新的结构（Pbcm, Z = 4）。
Three new alkali metal acetylides CsNaC2, CsKC2, and CsRbC2 have been synthesized and characterized by means of synchrotron powder diffraction studies. As a new synthetic approach, the binary alkali metal acetylides were reacted at relatively low temperatures (200 °C). DSC measurements were performed to prove the general usability of this reaction. CsKC2 and CsRbC2 crystallize in a variant of the anti-PbCl2-type structure (Pnma, Z = 4), while for CsNaC2 a new structure type (Pbcm, Z = 4) is found.
