Gold heptafluoride is a gold(V) compound with the empirical formula AuF₇. The synthesis of this compound was first reported in 1986. Current calculations suggest that it may be the first difluorine complex, AuF₅·F₂. The gold(V) difluorine complex is calculated to be 205 kJ/mol more stable than gold(VII) fluoride. The vibrational frequency at 734 cm⁻¹ is the hallmark of the end-on coordinated difluorine molecule.
