The bifluoride ion has a linear, centrosymmetric structure (D ∞h symmetry), with an F−H bond length of 114 pm. [1] The bond strength is estimated to be greater than 155 kJ/mol. [2] In molecular orbital theory, the atoms are modeled to be held together by a 3-center 4-electron bond (symmetrical hydrogen bond), [3] in a sort of hybrid between a hydrogen bond and a covalent bond.
Ammonium bifluoride, as its name indicates, contains an ammonium cation ([NH 4] +), and a bifluoride (or hydrogen difluoride) anion ([HF 2] −).The triatomic bifluoride anion features a strong three-center four-electron bond with a bond energy greater than 155 kJ/mol, [2] and an H-F length of 114 pm. [3]
Potassium bifluoride is the inorganic compound with the formula K[HF 2].This colourless salt consists of the potassium cation (K +) and the bifluoride anion ([HF 2] −).The salt is used as an etchant for glass.
The fluoronium ion is an inorganic cation with the chemical formula H 2 F +It is one of the cations found in fluoroantimonic acid. [1] The structure of the salt with the Sb 2 F − 11 anion, has been determined.
According to The New York Times, the Army has started to "wikify" certain field manuals, allowing any authorized user to update the manuals. [4] This process, specifically using the MediaWiki arm of the military's professional networking application, milSuite, was recognized by the White House as an Open Government Initiative in 2010.
