“…Although these structures correspond to a different packing density of the quasi-molecules, the distance between the chlorine and gold atoms (Au*–Cl*) is equal to ≈2.3 Å for all calculated configurations. This value is close to the distances between gold and chlorine atoms in the dimer (AuCl 3 ) 2 (2.24, 2.34 Å). − The distance between the chlorine atom in AuCl 2 and the nearest gold atom from the substrate (Cl*–Au s ) is slightly larger (2.65, 2.67 Å). The distances between gold atoms (Au*–Au*) in the dimers (AuCl 2 ) 2 and in the honeycomb structure equaled 3.49 and 3.56 Å, respectively, and roughly correspond to the Au–Au distance in (AuCl 3 ) 2 (3.42 Å).…”

Équipe 102 : Surfaces et SpectroscopiesInternational audienceAdsorption of molecular chlorine on Au(111) has been studied with a low-temperature (5 K) scanning tunneling microscope in combination with density functional theory calculations. The formation of AuCl2 quasi-molecules was detected at chlorine coverage exceeding 0.33 ML. The self-organization of the AuCl2 species into the ordered ``honeycomb'' structure was clearly demonstrated for coverages close to saturation

“…Gold monochloride consists of −Au–Cl–Au–Cl– chains . Gold trichloride exists always as Au 2 Cl 6 molecules which form a molecular crystal in the solid state. − Because each oval-shaped object contains at least two chlorine atoms, the AuCl model was excluded from our DFT analysis.…”

“…Experimental data is available3 for AuF 3 (electron diffraction) and shows clearly that it has T‐shaped geometry in the gas phase. In a recent study combining matrix‐isolation electronic absorption, IR, and AuL 3 ‐edge EXAFS, it was shown that AuCl 3 also has a T‐shaped geometry as a result of Jahn–Teller distortion 7. This observation is consistent with the suggestion of Schultz and Hargittai that AuF 3 and AuCl 3 are static Jahn–Teller systems 1.…”

“…Another highly relevant aspect of the coordination chemistry of Au I is its strong preference for the coordination number two, most notably in phosphane complexes 76–79. Although higher coordinate gold–phosphane complexes are known, gold is the least predisposed amongst the Group 11 elements to increase its coordination number any further 75.…”

The ability of platinum and gold catalysts to effect powerful atom-economic transformations has led to a marked increase in their utilization. The quite remarkable correlation of their catalytic behavior with the available structural data, coordination chemistry, and organometallic reactivity patterns, including relativistic effects, allows the underlying principles of catalytic carbophilic activation by pi acids to be formulated. The spectrum of reactivity extends beyond their utility as catalytic and benign alternatives to conventional stoichiometric pi acids. The resulting reactivity profile allows this entire field of catalysis to be rationalized, and brings together the apparently disparate electrophilic metal carbene and nonclassical carbocation explanations. The advances in coupling, cycloisomerization, and structural reorganization--from the design of new transformations to the improvement to known reactions--are highlighted in this Review. The application of platinum- and gold-catalyzed transformations in natural product synthesis is also discussed.
