In chemistry, a phosphide is a compound containing the P 3− ion or its equivalent. Many different phosphides are known, with widely differing structures. [ 1 ] Most commonly encountered on the binary phosphides, i.e. those materials consisting only of phosphorus and a less electronegative element.
Structural formula of Na 2 HPO 3.The anion has C 3v symmetry.. From the commercial perspective, the most important phosphite salt is basic lead phosphite.Many salts containing the phosphite ion have been investigated structurally, these include sodium phosphite pentahydrate (Na 2 HPO 3 ·5H 2 O).
Sodium phosphide is the inorganic compound with the formula Na 3 P. It is a black solid. It is often described as Na + salt of the P 3− anion. [2] Na 3 P is a source of the highly reactive phosphide anion. It should not be confused with sodium phosphate, Na 3 PO 4.
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 ...
Lithium phosphide is an inorganic compound of lithium and phosphorus with the chemical formula Li 3 P. This dark colored compound is formally the lithium salt of phosphine, consisting of lithium cations Li + and phosphide anions P 3−. It is hazardous to handle because of its high reactivity toward air. [1]
A Phosphide chloride is a mixed anion compound containing both phosphide (P 3−) and chloride (Cl −) ions. A common structural element is P 7 3− which is called heptaphosphanortricyclane with a formal IUPAC name of heptaphosphatricyclo[2.2.1.0 2,6]heptane. [1] Group 12 elements, cadmium and mercury are in most of the known compounds.
Related compounds include phosphide silicides, germanide phosphides, arsenide carbides, nitride carbides and silicide carbides. In light rare earth phosphide carbides, the ethenide ion [C=C] 4− exists. In these P and C 2 are disordered, and they randomly substitute for each other, even though charge differs. Bonds between carbon and ...
A phosphate phosphite is a chemical compound or salt that contains phosphate and phosphite anions (PO 3 3-and PO 4 3-).These are mixed anion compounds or mixed valence compounds. ...
