what is the electron domain geometry about phosphorus in the hexafluorophosphate anion (pf 6 ​ − )?
octahedral
hexafluorophosphate









































hexafluorophosphate is an anion with chemical formula of . it is an octahedral species. it imparts no color to its salts. is isoelectronic with sulfur hexafluoride, sf, and the hexafluorosilicate dianion, , and fluoroantimonate . being poorly nucleophilic, hexafluorophosphate is classified as a non-coordinating anion. 









































section::::synthesis.









































hexafluorophosphate salts can be prepared by the reaction of phosphorus pentachloride and alkali or ammonium halide in a solution of hydrofluoric acid:
hexafluorophosphate
ammonium hexafluorophosphate









































ammonium hexafluorophosphate is the inorganic compound with the formula nhpf. it is a white water-soluble, hygroscopic solid. the compound is a salt consisting of the ammonium cation and hexafluorophosphate anion. it is commonly used as a source of the hexafluorophosphate anion, a weakly coordinating anion. it is prepared by combining neat ammonium fluoride and phosphorus pentachloride. alternatively it can also be produced from phosphonitrilic chloride:
