The (EnH2)[AuCl4]2×2H2O (I) and (EnH2)2[AuCl4]Cl3 (II) (EnH22+ is diprotonated ethylenediamine) complexes are produced and characterized by elemental and thermogravimetric analysis, X‑ray diffraction, IR and Raman spectroscopy. For I, the crystals are monoclinic, crystallize in the space group P21/c: a = 7.5870(2) Å, b = 9.5665(2) Å, c = 11.4706(3) Å, β = 107.0480(10)°, V = 795.97(3) Å3, Z = 4. For II, the crystals are orthorhombic, crystallize in the space group Pnma : a = 12.7088(3) Å, b = 17.7435(5) Å, c = 7.4992(2) Å, V = 1691.06(8) Å3, Z = 8.
