Nitrogen trifluoride is the inorganic compound with the formula (NF 3). It is a colorless, non-flammable, toxic gas with a slightly musty odor. In contrast with ammonia, it is nonbasic. It finds increasing use within the manufacturing of flat-panel displays, photovoltaics, LEDs and other microelectronics. [6] NF
Trifluoramine oxide was first discovered in 1966 independently by two different groups. One way to produce it was by an electric discharge in a mixture of oxygen on nitrogen trifluoride. Another even less yielding method is by reacting noble metal fluorides (IrF 6 or PtF 6) with nitric oxide. [1]
The T-shaped geometry is related to the trigonal bipyramidal molecular geometry for AX 5 molecules with three equatorial and two axial ligands. In an AX 3 E 2 molecule, the two lone pairs occupy two equatorial positions, and the three ligand atoms occupy the two axial positions as well as one equatorial position. The three atoms bond at 90 ...
Structure of boron trifluoride, an example of a molecule with trigonal planar geometry. In chemistry , trigonal planar is a molecular geometry model with one atom at the center and three atoms at the corners of an equilateral triangle , called peripheral atoms, all in one plane. [ 1 ]
In a tetrahedral molecular geometry, a central atom is located at the center with four substituents that are located at the corners of a tetrahedron. The bond angles are arccos (− 1 / 3 ) = 109.4712206...° ≈ 109.5° when all four substituents are the same, as in methane ( CH 4 ) [ 1 ] [ 2 ] as well as its heavier analogues .
Tetrafluorohydrazine was originally prepared from nitrogen trifluoride using a copper as a fluorine atom acceptor: [3] 2NF 3 + Cu → N 2 F 4 + CuF 2. A number of F-atom acceptors can be used, including carbon, other metals, and nitric oxide. These reactions exploit the relatively weak N-F bond in NF 3. [4]
The commonplace molecular nitrogen (N 2) was first isolated by Daniel Rutherford in 1772 [1] and the azide ion (N − 3) was discovered by Theodor Curtius in 1890. [2] Discoveries of other related nitrogenous allotypes during the twentieth century include the aromatic molecule pentazole and the radical molecule N • 3.
The reaction of nitrogen trifluoride with fluorine and boron trifluoride at 800 °C yields the tetrafluoroborate salt: [6] NF 3 + F 2 + BF 3 → NF 4 BF 4. NF + 4 salts can also be prepared by fluorination of NF 3 with krypton difluoride (KrF 2) and fluorides of the form MF n, where M is Sb, Nb, Pt, Ti, or B. For example, reaction of NF 3 with ...
