Tetraethylammonium diiron oxyhexachloride is the chemical compound with the formula (N(C₂H₅)₄)₂Fe₂OCl₆. It is the tetraethylammonium salt of [Fe₂OCl₆]^2-. Many related salts of [Fe₂OCl₆]^2- are known. The anion consists of a pair of tetrahedral Fe(III) centers that share a oxo bridging ligand.^[2] The salt can be prepared by treatment of tetraethylammonium tetrachloroferrate with sodium trimethylsiloxide.^[1]
