Physical Properties:
Gold trichloride is characterized by its red monoclinic crystals, which deliquesce and sublime at 180°C (760 torr). It has a density of 4.7 g/cm3 and is highly soluble in water, soluble in alcohol and ether, and slightly soluble in liquid ammonia.
Chemical Properties:
Gold trichloride exists as a dimer, Au2Cl6, and its crystals range from orange-red to dark red. It decomposes easily at 175°C to form gold(I) chloride and chlorine, and at higher temperatures, it decomposes to produce gold and chlorine.

Preparation

Gold(III) chloride may be produced by the combination of metallic gold with chlorine gas at elevated temperatures: 2Au + 3Cl2 → 2AuCl3 It may be prepared in the laboratory by the reaction of iodine monochloride with metallic gold: 2Au + 6ICl → 2AuCl3 + 3I2 The compound should be stored tightly closed and protected from light.

Reactions

When heated at 254oC, gold(III) chloride decomposes to gold(I) chloride and chlorine. Passing hydrogen sulfide into an ether solution of the compound yields gold(III) sulfide, Au2S3. A similar reaction occurs when alcoholic solutions of gold(III) chloride and hydrogen selenide are mixed, producing gold(III) selenide, Au2Se3, a black amorphous solid. Gold(III) chloride may be reduced readily to metallic gold by common reducing agents. Thus, reduction with stannous chloride in dilute aqueous medium yields colloidal gold in which the atom carries a negative charge. “Cassius purple” is produced from the oxidation of tin to form H2Sn(OH)6, which protects colloidal gold from coagulation, imparting ruby red color to the solution. Gold(III) chloride reacts with ammonia forming a gold(III)-nitrogen derivative, an explosive product, known as, “fulminate of gold”. Reaction with Grignard reagent, RMgX in ether yields dialkyl gold(III) chloride, R2AuCl3, which may be converted readily to other dialkyl gold(III) complexes by replacement of the chloride anion by a donor ligand.

Safety Profile

Experimental reproductive effects. Human mutation data reported. Reaction with ammonia or ammonium salts yields fulminating gold, a heat-, friction-, and impact-sensitive explosive similar to mercury and silver fulminates. See also GOLD COMPOUNDS and CHLORIDES. When heated to decomposition it emits toxic fumes of Cl-.

Synthesis and structure of MII[AuF4]2 (MII = Cd, Hg)

Cd[AuF4]2 and the isotypic compound Hg[AuF4]2, both are yellow, crystallize tetragonal in the space-group P4/mcc-D24h (No. 124) with a = 575.0/575.6 pm, c = 1034.8/ 1042.3 pm and Z = 2. The single-crystals were obtained by solid-state reactions in goldtubes.

On the crystal structure of La[AuF4]3, the final link in the series M[AuF4]3-xFx (x = 0, 0.5 and 1)

Yellow La(AuF4)3 was prepared for the first time in form of single crystals and investigated by X-ray methods. It crystallizes in space group R3c-D3d6 (Nr. 167) with a = 1056.2(2) pm, c = 1633.7(8) pm, Z = 6. Johann Ambrosius Barth 1996.

Improvement of photocatalytic activity of titanium (IV) oxide by dispersion of Au on TiO2

The photocatalytic oxidation of organic compounds in an aqueous solution containing a suspension of titanium(IV) oxide is a comparatively new method for removing impurities from water. TiO2 samples were prepared by two procedures, and their catalytic activities in the degradation of 1,4-dichlorobenzene were compared to samples of commercial TiO2. It was found that the dispersion of gold onto the surface of the oxide powders greatly increased their photocatalytic activity.

A green paramagnetic gold fluoride - Sn1-xAuxF4?

Green single crystals were obtained by heating (Au-tube, 450°-500°C) a mixture of SnF2 and AuF3 (Sn:Au = 1:1) which correspond to the SnF4-type [2, 3] (two single crystals, A: 762 Io, R1 = 2.4%; B: 1591 Io, R1 = 1.2% (SHELXL=93); I4/mmm (No. 139); B: a = 404.8(1) pm, c = 796.4(1) pm, c/a = 1.97, zF2 = 0.2354). Due to atom absorption and Moessbauer measurements the crystals contain Au. The compound is paramagnetic and follows the Curie-Weiss law (14.7-251.3 K, θ = -12K, μ/μB = 1.55). ESR-experiments confirm that Au is surrounded by 6 F- according to Sn in SnF4 (2 short (187.5 pm) and 4 longer (202.4 pm) distances). The observed Moessbauer spectra could not be interpreted yet, but they don't correspond to any known. Johann Ambrosius Barth 1996.

In the system MF3/AuF3 the structures of several yellow Tetrafluoroaurates(III) have been determinated. TlF2[AuF4] crystallizes tetragonal, space group P41212 - D44 (Nr. 92) with a = 573.17(4) pm, c = 2780.4(3) pm, Z = 8; M2F[AuF4]5 (M = Bi, La) tetragonal, space group P41212 - D44 (Nr. 92) with a = 822.89(5) pm, c = 2557.1(3) pm, Z = 4 (Bi); with a = 836.80(3) pm, c = 2602.2(2) pm, Z = 4 (La); Y2F[AuF4]5 monoclin, space group P2/n - C2h4 (Nr. 13) with a = 1188.9(3) pm, b = 797.4(2) pm, c = 895.7(3) pm, β = 89.18(3), Z = 4 and Sm[AuF4]3 trigonal, space group R3c - D3d6 (Nr. 167) with a = 1034.5(1) pm, c = 1614.1(3) pm, Z = 6. All these yellow crystals have been obtained by solid state reactions in autoclaves or sealed goldtubes.

Rh2Cl2(CO)4 adsorbed and tethered on gold powder: IR spectroscopic characterization and olefin hydrogenation activity

Catalysts were prepared by adsorbing Rh2Cl2(CO)4 directly on gold powder or on gold that contained the tethered ligands 2-(diphenylphosphino)ethane-1-thiol (DPET) or methyl 2-mercaptonicotinate (MMNT). Infrared (IR) studies (diffuse reflectance infrared Fourier transform (DRIFT)) of the catalyst Rh-Au prepared by adsorbing Rh2Cl2(CO)4 directly on Au indicate that a RhI(CO)2 species is present. IR studies of Rh-DPET-Au suggest that tethered cis-Rh(DPET)(CO)2Cl is the major species at relatively high Rh2Cl2(CO)4 loadings, but trans-Rh(DPET)2(CO)Cl is observable at low Rh2Cl2(CO)4 loadings. Spectral investigations of the catalyst Rh-MMNT-Au prepared by adsorbing Rh2Cl2(CO)4 on MMNT-Au suggest that tethered [cis-Rh(MMNT)2(CO)2]+Cl- and (or) Rh(MMNT)(CO)2Cl are the major species at low Rh2Cl2(CO)4 loadings, while a new unidentified species predominates at high Rh2Cl2(CO)4 loadings. All three catalysts are active 1-hexene hydrogenation catalysts under the mild conditions of 40°C and 1 atm of H2; they are much more active than Au powder or Rh2Cl2(CO)4 in solution. Of the three catalysts, Rh-Au is the most active with a maximum turnover frequency (TOF) of 800 mol H2 per mol Rh per min while its turnover (TO) is 29 600 mol H2 per mol Rh during a 2-hour run. Under the conditions of 1-hexene hydrogenation, the catalysts lose their CO ligands. Thus, it appears that a form of Rh metal on Au is the catalytically active species.

Synthesis and structure of MII[AuF4]2 with MII = Ni, Pd

Yellow Ni[AuF4]2, obtained as single crystals by solvothermal synthesis in anhydrous HF crystallizes monoclinic, isotypic to M[AuF4]2 (M = Mg, Zn) [1], space group P21/c-C52h (No. 14) with a = 550.4, b = 546.0, c = 1083.1 pm and β = 109.47°. In order to get better comparison to Pd[AuF4]2 it will be described in the space group P21/n with a = 550.4 pm, b = 546.0 pm, c= 1038.2 pm, β = 100.47° and Z = 2. Green Pd[AuF4]2, prepared by heating a mixture of PdF2 and AuF3 in sealed Au-tubes crystallizes also monoclinic, space group P21/c (setting P21/n with a = 519.79 pm, b = 1095.7 pm, c = 555.7 pm, β = 89.93° and Z = 2), but it is not isotypic to Ni[AuF4]2.

Lewis-acid-base-reactions of gold trihalides with bismuth trihalides - Synthesis and structures of AuBiX6 (X = Cl, Br)

Gold trihalides AuX3 (X = Cl, Br) react with bismuth trihalides in sealed glass ampoules to the 1:1 adducts AuBiX6 (X = Cl, Br). AuBiCl6 is obtained by a chemical transport reaction at 220 °C, whereas AuBiBr6 was synthesized by solvothermal reaction in SiBr4 at 1.50 °C. Both compounds crystallize triclinic, space group P1?, Z = 4, AuBiCl6: a = 698.3(4) pm; b = 1009.3(5) pm; c = 1381(1) pm; α = 104.98(5)○; β = 94.73(5)○; γ = 110.06(3)○; V = 867(1) · 106 pm3. AuBiBr6: a = 735.7(4) pm; b = 1055.7(5) pm; c = 1445(1) pm; α = 104.88(5)○; β = 94.25(5)○; γ = 110.18(4)○; V = 1001(1) · 106 pm3. The structures are build formally of square-planar [AuX4]- and chains of edge-connected ([BiX4/2]+)n units. Since each Bi ion is surrounded by eight halogenide ions in a square-antiprismatic form, the structure can alternatively be described as consisting of chains of edge sharing ([BiX4X4/2]3-)n antiprisms connected by Au3+ ions.

Valence of Au in AuTe2 and AuSe studied by x-ray absorption spectroscopy

The gold compounds AuTe2 and AuSe contain Au atoms in two different chemical surroundings. In the literature these different coordinations have been associated with a difference in valency of the Au atoms. In this paper the occupation of the 5d shell in AuSe and AuTe2 is deduced from a study of the 4f → 5d X-ray absorption edge. A comparison is made with the absorption edges of Au, AuCl and AuCl3. The results show that only AuCl3 has Au atoms in a valence state of III, and that the Au atoms in AuTe2 and AuSe are all in the same monovalent state I, independent of their chemical environment.
