The reaction of Cs3As7with diphenylacetylene in the presence of 18crown‐6 in liquid ammonia results in the formation of the new compound [Cs(18crown‐6)]2As7C14H11·6NH3, which crystallizes in black monoclinic crystals. It contains the first monosubstituated heptaarsenide anion with a hydrocarbon‐only substituent and theoretical calculations show a significant influence of the organic substituent on the electronic structure within the cage. The (Z)‐1, 2‐diphenylethenyl‐heptaarsenide di‐anion can be seen as the first step towards the formation of 1, 2,3‐triarsolides. Further experiments regarding the reaction of Rb3As11and Cs3As11with acetylene gas in liquid ammonia reveal the formation of the diarsabarrelene As2C6H6, which crystallizes as colorless orthorhombic crystals. Calculations based on the structural data obtained by X‐ray crystallography show the electronically inert character of the arsenic lone pair.
