Article abstract of DOI:10.1039/DT9840000285

The reaction of n4> (R=C6F5 or C6F3H2-2,4,6) with Ag leads to complexes <n>, which react with neutral ligands to give complexes <n> (L=neutral O-, N-, S- or P-donor ligand, alkene, or alkyne).For R=C6F5 and L=diphenylacetylene, the product is <n>; the 0.5L can be displaced by other ligands, such as acetone, arenes, or alkenes, to reform <n>.An X-ray diffraction study of <n> (R=C6F5, L=tetrahydrothiophene) reveals (AuAg)2 rings with Au-Ag 2.726 and 2.718 Angstroem (the first reported Au-Ag bond lengths), linked by Au...Au short contacts (2.889 Angstroem) to form infinite metal-atom chains.This complex crystallizes in space group Pccn, with a=11.185(3), b=22.475(6), c=14.802(4) Angstroem, Z=8, R=0.041 for 2 005 reflections.The complex <n> (R=C6F5, L=benzene) crystallizes in space group C2/c, with a= 24.231(5), b=7.570(1), c=22.613(5) Angstroem, β=117.49(2) deg, Z=8, and R=0.035 for 3 008 reflections; it shows the same type of metal-atom chain (Au...Au 3.013; Au-Ag 2.702 and 2.792 Angstroem).The benzene ring is co-ordinated by one edge to silver.In both structures the gold atoms lie on a crystallographic two-fold axis.
