Abstract

In the reaction of P2H4 with n-BuLi the product pattern strongly depends on the stoichiometric ratio and the reaction temperature (-25 °C or -78 °C). The following polyphosphides have been detected by 31P NMR spectroscopy: LiH8P7, LiH4P7, LiH5P8, Li2H2P14, LiH2P7, Li2HP7, Li3P7, LiH4P5, LiH4P3, LiH3P2, and a still unidentified compound LixHyPz.
