Copper phosphide, Cu3P, also copper(I) phosphide, cuprous phosphide, cuprophosphorus and phosphor copper, is a compound of copper and phosphorus, a phosphide of copper. It has the appearance of yellowish-grey very brittle mass of crystalline structure. It does not react with water.
Recent crystallographic investigations have proven Cu3P to be copper deficient, which means that the sum formula of this compound is more accurately expressed as Cu3−xP.[4]
Copper phosphide has a role in
Copper phosphide can be produced in a reverberatory furnace or in a crucible, e.g. by a reaction of red phosphorus with a copper-rich material. It can also be prepared photochemically, by irradiating cupric hypophosphite with ultraviolet radiation.[5] It can also be produced by reducing copper(II) phosphate with aluminum.[6]
When subjected to ultraviolet light, copper phosphide shows fluorescence.
