Copper(II) tetrafluoroborate is the copper salt of tetrafluoroboric acid which involves copper in its +2 oxidation state bonded to two tetrafluoroborate anions (BF₄⁻). Tetrafluoroborate adopts a tetrahedral shape, similar to that of methane. The central boron atom has a formal charge of −1, because of its four covalent bonds. Its oxidation state is +3.^[2]
