Abstract
Heating of a mixture of white phosphorus and sodium in diethylene glycol dimethyl ether in the presence of catalytic amounts of dibenzo-18-crown-6 affords a pure solution of sodium pentaphosphacyclopentadienide NaP5. One of the intermediate products is trisodium heptaphosphide Na3P7. The influence of the nature of a metal (Li, Na, K) on the formation of the pentaphosphacyclopentadienide anion was studied.
