Sodium Tetraphenylborate is an organic boron-containing salt with the chemical formula C24H20BNa. Its tetraphenylborate anion consists of a central boron atom bonded to four phenyl groups. It occurs as a white crystalline solid and is valued for forming stable, often crystalline salts with selected cations. The tetraphenylborate ion has a diffuse negative charge and behaves as a weakly coordinating anion, making the compound particularly useful in analytical, inorganic and organometallic chemistry.
