Tetrafluoroammonium
The tetrafluoroammonium cation (also known as perfluoroammonium) is a positively charged polyatomic ion with chemical formula . It is equivalent to the ammonium ion where the hydrogen atoms surrounding the central nitrogen atom have been replaced by fluorine. Tetrafluoroammonium ion is isoelectronic with tetrafluoromethane , trifluoramine oxide and the tetrafluoroborate anion. The tetrafluoroammonium ion forms salts with a large variety of fluorine-bearing anions. These include the bifluoride anion (), tetrafluorobromate (), metal pentafluorides ( where M is Ge, Sn, or Ti), hexafluorides ( where M is P, As, Sb, Bi, or Pt), heptafluorides ( where M is W, U, or Xe), octafluorides (), various oxyfluorides ( where M is W or U; , ), and perchlorate (). Attempts to make the nitrate salt, , were unsuccessful because of quick fluorination: + → + . Structure The geometry of the tetrafluoroammonium ion is tetrahedral, with an estimated nitrogen-fluorine bond length of 1 ...

Tetrafluoroammonium Ion
The tetrafluoroammonium cation An ion () is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convent ... (also known as perfluoroammonium) is a positively charged polyatomic ion with chemical formula . It is equivalent to the ammonium ion where the hydrogen atoms surrounding the central nitrogen atom have been replaced by fluorine. Tetrafluoroammonium ion is isoelectronicity, isoelectronic with tetrafluoromethane , trifluoramine oxide and the tetrafluoroborate anion. The tetrafluoroammonium ion forms salt (chemistry), salts with a large variety of fluorine-bearing anions. These include the bifluoride anion (), tetrafluorobromate (), metal pentafluorides ( where M is germanium, Ge, tin, Sn, or titanium, Ti), hexafluorides ( where M is phosphorus, P, arsenic, As, antimony, Sb, bismuth, Bi, or platinum, P ...
