'''Silver tetrafluoroborate''' is an [[inorganic compound]] with the chemical formula AgBF<sub>4</sub>. 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}}

==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. Geiger| title=Chemical Redox Agents for Organometallic Chemistry|journal=[[Chemical Reviews]]|year= 1996| volume= 96|issue=2| pages= 877–910| doi=10.1021/cr940053x| pmid=11848774}}</ref> Similar to [[silver hexafluorophosphate]], it is commonly used to replace [[halide]] anions or ligands with the [[non-coordinating anion|weakly coordinating]] [[tetrafluoroborate]] anions. The abstraction of the halide is driven by the precipitation of the corresponding [[silver halide]].
