The reaction between - and tetrahydrothiophene (tht) in the presence of NaClO4 gives a solution (probably containing ) that can be used to prepare neutral n> (L = AsPh3, n = 1; L = SbPh3, n = 2; L = 1,10-phenanthroline, n = 1) or anionic - complexes.Treatment of with chlorine or PhICl2 gives trans- or cis-.Isomerizations occur when the cis-isomer is treated with concentrated solutions of chlorine or when the trans-isomer is heated.An X-ray diffraction study of has revealed an almost linear coordination around the gold atom (As-Au-C mean value 177(2) deg).The Au-O distance is too long (mean value 2.80(3) Angstroem) for intramolecular coordination.

Treatment of with (x=o, m, or p) gives anionic gold(I) complexes of the type (R=o-, m- or p-C6H4NO2, Bz=C6H5CH2).The chloro ligand in - can be replaced by bromo or iodo ligands by use of NaBr or NaI.The anions - react with neutral monodentate ligands, L, to give neutral mononuclear complexes (R=o-C6H4NO2, L=PPh3, AsPh3; R=m-C6H4NO2, L=PPh3) and with 1,2-bis(diphenylphosphino)ethane (dpe) to give (R=o-C6H4NO2).The corresponding - reacts with PPh3 or AsPh3 to give mixtures containing .The anionic ortho-nitrophenylgold(I) complex is much more stable than its meta- or para-nitrophenyl isomers.These are thought to be the first reports of nitrophenylgold(I) complexes.
