摘要：

Reactions of the heterobimetallic complexes [(OC)3{(MeO)3Si}Fe(mu-PPh2)Pt(PPh3)2] (1) and [(OC)3{(MeO)3S}Fe(mu-PR2)Pt(1,5-COD)] (3a, R = Ph) with HBF4 . Et2O result in cleavage of the Fe-Si bond and formation of the dihydrido complexes [(OC)3Fe(mu-PPh2)(mu-H)2Pt(PPh3)2][BF4] (2) and [(OC)3Fe(mu-PR2)(mu-H)2Pt(1,5-COD)][BF4] (4), respectively. Reactions of 3a or 3b (R = Cy) with [(Ph3P)Au][PF6] reqUiTed 2 equiv. of the electrophile to give the clusters [(OC)3Fe(mu-PR2){mu-Au(PPh3)}2Pt(1,5-COD)][PF6] (5a, R = Ph; 5b, R = Cy). These were fully characterised and the structure of 5b was determined by X-ray diffraction: crystals are monoclinic, space group P2(1)/n, a = 22.479(6), b = 26.781(8), c = 10.254(3) angstrom, beta = 102.94(2)-degrees, U = 6016.1 angstrom3 and Z = 4. This is the first structural determination of a heterobimetallic complex carrying two Au-fragments. The Fe-Pt bond (2.715(3) angstrom) is bridged by a mu-PCy2 group and by two Au(PPh3) fragments. No Au-Au interaction is observed (4.333(1) angstrom).
