摘要：

Reaction of [Ru-2(CO)(6)(mu-PPh(2))(mu-eta(1),eta(alpha,beta)(2)-C=C-C=CR)] (R = Bu(t) 1a, Ph 1b) with the labile complexes [Pt(PPh(3))(2)(eta-C2H4], [Pt(dppb)(eta-C2H4)] and [Ni(cod)(2)] or [Ni(CO)(4)] leads to the heteronuclear derivatives [Ru2Pt(CO)(7)(PPh(3))(mu(3)-eta(1),eta(1),eta(1)-C=C-C=CR)(mu-PPh(2))] 2a,b, [Ru2Pt(CO)(6)(dppb)(mu(3)-eta(1),eta(1),eta(1)-C=C-C=CBu(t))(mu-PPh(2))] 2c and [Ru4Ni(CO)(12)(mu-PPh(2))(2)(mu(4)-eta(1),eta(1),eta(2),eta(4)-Bu(t)C=CC4C=CBu(t))] 3 resulting from addition of a PtL(2) fragment and Ni-assisted stoichiometric coupling of two molecules of 1a respectively; the X-ray crystal structures of 2a and 3 are described.
