摘要：

The mixed phosphine-phosphine oxide Ph2PCH2CH2P(O)Ph-2 (dppeO) reacts with either trans-[PdCl2(PhCN)(2)], Na-2[PdCl4] or trans-[PdCl2(DMSO)(2)] to give trans-[PdCl2{(1)eta -Ph2PCH2CH2P(O)Ph-2}(2)]. Treatment of the latter with the metal chlorides, MCl2 . nH(2)O (M = Mn, Cu, Co, Zn, Hg; n = 4, 2, 6, 1, 0, respectively) or with Me2SnCl2 or SnCl4 . 5H(2)O, or with UO2(NO3)(2) . 6H(2)O or UO2(OAc)(2) . 2H(2)O gives heterobimetallic complexes: trans-[PdCl2{mu -Ph2PCH2CH2P(O)Ph-2}(2)MX2] . nH(2)O. The cobalt complex (MX2 = CoCl2) was unstable in solution (MeOH or EtOH/CHCl3), and reverts to trans-[PdCl2{(1)eta -Ph2PCH2CH2P(O)Ph-2}(2)] and CoCl2. trans-[PdCl2{(1)eta -Ph2PCH2CH2P(O)Ph-2}(2)] does not apparently react with either NiCl2 . 6H(2)O or CdCl2 . 2.5H(2)O.
