This Review showcases the ability of bi- and tridentate ligands to stabilize gold in high oxidation states through the formation of mono- and biscyclometalated gold(III) complexes. In-depth studies on the synthesis, intrinsic reactivity, catalytic relevance, and photophysical properties of stabilized gold(III) species have been carried out, setting the stage for exciting developments in various research areas, such as catalysis, inorganic and bioinorganic chemistry, ligand design, and materials science.

Vapour and mechanically induced chromic behaviour of platinum complexes with a dimer-of-dimer motif and the effects of heterometal ions

Heterodinuclear complexes, syn- [MPt(-pyt) 2 (bpy) 2 ] n+ (syn- [MPt], M = Pd 2+ , Au 3+ , Hpyt = pyridine-2-thiol, bpy = 2,2′-bipyridine) were synthesized as a selective geometrical isomer by stepwise complexation. X-ray analyses of the hexafluorophosphate salts of these complexes proved their dinuclear structures with short M···Pt distances (2.9084(4) Å for syn- [PdPt] and 2.9071(4) Å for syn- [AuPt]), similar to the 10 homodinuclear complex (2.9292(2) Å for syn- [PtPt]). In the syn- [PdPt] crystal, two dinuclear motifs are arranged closely in a head-to-head manner with a short Pt···Pt distance (3.3757(3) Å), forming a dimerof-dimer structure as in the case of syn- [PtPt] 2 . The reversible structural transformations induced by the uptake and release of CH 3 CN molecules were investigated by powder and single-crystal X-ray diffraction studies. These revealed that the vapochromic behaviour was based on the interconversion between two phases, the dimer-of-dimer structure with a short Pt···Pt distance and a - stacked arrangement with no Pt···Pt 20 intermolecular interaction. The introduction of the hetero metal ions enabled control of the colour region: orange  red for syn- [PdPt] vs. light red  dark red for syn- [PtPt], reflecting the weaker metal-metal interaction between Pd 2+ and Pt 2+ ions in the dinuclear motif. In addition, these complexes were found to exhibit mechanochromic behaviour based on a crystal-to-amorphous transformation upon grinding, and the reconstruction of the crystal structures by vapour sorption.

In contrast to the related Au(I) (224,234,(241)(242)(243)(244)(245)(246)(247)(248)(249)(250)(251)(252)(253)(254)(255)(256), and the isoelectronic Pt(II) compounds (16,250,257,258) that show excellent luminescence properties, room temperature luminescent Au(III) compounds are rare with only a limited number of examples known (259)(260)(261). This same trend holds for alkynyl complexes; Au(I) (240-242, 246, 249) and Pt(II) species (16,262,263) are widely known and possess rich photoluminescence properties, while the number Au(III) examples is quite limited (257,259,264,265).…”
