Lithium phosphide is an inorganic compound of lithium and phosphorus with the chemical formula Li
3P. This dark colored compound is formally the Li+ salt of P3-. It is a hazardous to handle because of its high reactivity toward air.[1]
Heating red phosphorus and lithium in an argon atmosphere:[1]
Reaction of monolithium phosphide and lithium:
Lithium phosphide forms red-brown crystals of hexagonal systems, space group P63/mmc,[2] cell parameters a = 0.4264 nm, c = 0.7579 nm, Z = 2.[3][4]
The compound react with water to release phosphine:[5]
The compound is proposed to be used as a potential electrolyte for solid-state devices.[6]
Reaction of lithium with red phosphorus at 870 °C gives Li3P7.[7]
