It is a white solid that dissolves in polar organic solvents as well as water. In its solid state, the Ag<sup>+</sup> centers are bound to fluoride.<ref>Evgeny Goreshnik, Zoran Mazej, "X-ray single crystal structure and vibrational spectra of AgBF<sub>4</sub>" Solid State Sciences 2005, Volume 7, pp. 1225–1229. {{doi|10.1016/j.solidstatesciences.2005.06.007}} </ref> ==Preparation== Silver tetrafluoroborate is prepared by the reaction between [[boron trifluoride]] and [[silver oxide]] in the presence of [[benzene]]. ==Laboratory uses== In the [[inorganic chemistry|inorganic]] and [[organometallic chemistry]] laboratory, silver tetrafluoroborate, sometimes referred to "silver BF-4", is a useful [[reagent]]. In dichloromethane, silver tetrafluoroborate is a moderately strong oxidant.<ref>{{cite journal|author=N. G. Connelly, W. E.

The abstraction of the halide is driven by the precipitation of the corresponding [[silver halide]]. ==References== <references/> {{Silver compounds}} {{Tetrafluoroborates}} [[Category:Tetrafluoroborates]] [[Category:Silver compounds]] [[Category:Oxidizing agents]] {{inorganic-compound-stub}} |
