The reaction of (R=C6F5 or 2,4,6-C6F3H2) with Au(ONO2)PPh3, ClO4 or ClO4 (tht=tetrahydrothiophene) leads to neutral <(C6F5)Au(CH2PPh2CH2)2AuONO2> 1 or monocationic derivatives ClO4 .Complexes 3 and 5 react with anionic or neutral reagents, giving new neutral or monocationic gold(II) compounds.The structure of <(C6F5)Au(CH2PPh2CH2)2AuPPh3>ClO4*0.5CH2Cl2 (2) was determined by single-crystal X-ray diffraction.Crystals are triclinic, space group P<*>, a=12.468(2), b=13.493(2), c=18.283(3) Angstroem, α=108.13(1) deg, β=91.09(1) deg, γ=111.95(1) deg and Z=2.Final R is 0.0376 forb4906 unique observed reflections.The Au-Au bond length is 2.6612(8) Angstroem.
