摘要：

A new look into an old pot: A new cluster structure is found for the cage anion 1 (see picture, L = dme) in the salt [Na(dme3)] +[Na5(P2Ph2)(dme)3] -. This (structurally characterized) ionic compound is obtained in excellent yield when PhPCl2 is simply reduced with sodium in a toluene/tetramethylethylene mixture. This method delivers catena-oligophosphane-α,ω-diides with two, three, or four phosphorus atoms.
