In the thermal production of gold coatings on ceramics and glass, paints are used which comprise Au chloro-complexes and sulfur-containing resins dissolved in an organic solvent. It seems likely that polymeric species are responsible for rendering the gold soluble. 

The solution should be free from the following, which either interfere or lead to an unsatisfactory deposit silver, mercury, bismuth, selenium, tellurium, arsenic, antimony, tin, molybdenum, gold and the platinum metals, thiocyanate, chloride, oxidising agents such as oxides of nitrogen, or excessive amounts of iron(III), nitrate or nitric acid. Chloride ion is avoided because Cu( I) is stabilised as a chloro-complex and remains in solution to be re-oxidised at the anode unless hydrazinium chloride is added as depolariser.

The trinuclear gold(I) complexes [(AuX)3( j,-triphos)] (triphos = bis(2-diphenylphos-phinoethyl)phenylphosphine X = Cl, Br, I, CgFs ), where X = Br and I , were reported to emit at room temperature with emission energies significantly red-shifted from that ofthe free phosphine ligand (2477 cm for Br with Agx 350 nm 4482 cm for I with Aex 385 nm) [41]. The chloro, pentafluorophenyl, and l,3,5-tris(trifluor-omethyl)phenyl derivatives do not emit, even at Aex <300 nm. The emission properties...
