Gold phosphide is a hypothetical binary inorganic compound of gold metal and phosphorus with the chemical formula AuP.[1][2] No compound of composition AuP has been probed by X-ray crystallography. The only known gold phosphide is the metastable Au2P3.[3][4]

Preparation

edit

Gold phosphide was claimed to be prepared by the direct reaction of spongy gold and phosphorus or by passing phosphine into a solution of auric chloride in ether or alcohol:[5][6][7]

AuCl3 + PH3 → AuP + 3HCl

Properties

edit

AuP is claimed to decompose in air or with H2O.[8]

edit

A mixed anion phosphide iodide is known: Au7P10I with a trigonal structure.[4]
