Phosphide. A portion of the structure of Cu3P, highlighting the highly crosslinked nature common to many transition metal phosphides (Cu = orange, P = purple). In chemistry, a phosphide is a compound containing the P3− ion or its equivalent. Many different phosphides are known, with widely differing structures. [1]
Sodium phosphide is a source of the highly reactive phosphide anion. The material is insoluble in all solvents but reacts as a slurry with acids and related electrophiles to give derivatives of the type PM 3: [6] Na 3 P + 3 E + → E 3 P (E = H, Me 3 Si) The trimethylsilyl derivative is volatile (b.p. 30-35 C @ 0.001 mm Hg) and soluble.
Phosphine is an attractive fumigant because it is lethal to insects and rodents, but degrades to phosphoric acid, which is non-toxic. As sources of phosphine, for farm use, pellets of aluminium phosphide (AlP), calcium phosphide (Ca 3 P 2), or zinc phosphide (Zn 3 P 2) are used. These phosphides release phosphine upon contact with atmospheric ...
Calcium phosphide (CP) is the inorganic compound with the formula Ca 3 P 2. It is one of several phosphides of calcium, being described as the salt-like material composed of Ca 2+ and P 3−. Other, more exotic calcium phosphides have the formula CaP / Ca 2 P 2, CaP 3, and Ca 5 P 8. Ca 3 P 2 has the appearance of red-brown crystalline powder or ...
Potassium phosphide is an inorganic semiconductor compound with the formula K 3 P. It appears as a white crystalline solid or powder. [ 2 ] It reacts violently with water and is toxic via ingestion, inhalation and skin absorption. [ 3 ]
Aluminium phosphide is a highly toxic inorganic compound with the chemical formula AlP, used as a wide band gap semiconductor and a fumigant. This colorless solid is generally sold as a grey-green-yellow powder due to the presence of impurities arising from hydrolysis and oxidation .
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 Cu 3 P to ...
Iron phosphide is a chemical compound of iron and phosphorus, with a formula of FeP.< [ 1] Its physical appearance is grey needles. Manufacturing of iron phosphide takes place at elevated temperatures, where the elements combine directly. [ 1] Iron phosphide reacts with moisture and acids producing phosphine (PH 3 ), a toxic and pyrophoric gas.
