In solid |[NH4][HF2], each ammonium cation is surrounded by four fluoride centers in a tetrahedron, with hydrogen fluorine hydrogen bonds present between the hydrogen atoms of the ammonium ion and the fluorine atoms. Solutions contain tetrahedral [[ammonium||[NH4]]]+ cations and linear |[HF2]− anions.

Ammonium bifluoride is toxic to consume and a skin corrosion agent. Upon exposure to skin, rinsing with water followed by a treatment of calcium gluconate is required. Consequently, there is an equivalent toxicological risk as is present with hydrofluoric acid, and the same safety precautions apply. Ammonium bifluoride based products are often considered a safer alternative to hydrofluoric acid, yet still pose clear risks to the handler. advice that accords with a 2015 report from the U. S. Centers for Disease Control and Prevention.
