Description
Strontium phosphide has the molecular formula of
Sr3P2 and the molecular weight of 324.8075 g/mol. Its
CAS number is 12504-13-1. It is a black crystalline material
with a melting point of 1205°C. Its density is
2.71 g/cm3. It readily reacts with water to form phosphine,
PH3, but is insoluble in ethanol.
It is easily prepared by reacting the metal with red
phosphorus at high temperature. The best way is to
sublime the P4 at 450°C in an inert gas stream and react
it with Sr metal at 650°C:
6Sr + 2P4 ? 2Sr3P4
Strontium phosphide is a solid which will evolve
flammable and toxic gases on contact with water. It
also can react vigorously with oxidizing materials. In
general, materials in this group are incompatible with
oxidizers such as atmospheric oxygen. They are
violently incompatible with acids, particularly oxidizing
acids.
