摘要：

The reaction of [RAu(CH2PPh2CH2)2AuR] (R = C6F5 or 2,4,6-C6F3H2) with Au(ONO2)PPh3, [Au(PPh3)2]ClO4 or [Au(PPh3)tht]ClO4 (tht = tetrahydrothiophene) leads to neutral [(C6F5)Au(CH2-PPh2CH2)2AuONO2] 1 or monocationic derivatives [RAu(CH2PPh2CH2)2AuL]ClO4 [R = C6F5, L = PPh3(2) or tht(3); R = 2,4,6-C6F3H2, L = PPh3(4) or tht(5)]. 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 P1BAR, a = 12.468(2), b = 13.493(2), c = 18.283(3) angstrom, alpha = 108.13(1)-degrees, beta = 91.09(1)-degrees gamma = 111.95(1)-degrees and Z=2. Final R is 0.0376 for 4906 unique observed reflections. The Au-Au bond length is 2.6612(8) angstrom.
