behavior of the polydentate ligand bis(1,2,4-diazaphospholyl)methane (Bdapm) toward group 6 and group 10 metals has been studied. From the reaction with [W(CO)5(NMe3)], three species with different coordination patterns were isolated and characterized. Thus we proved that the polydentate Bdapm ligand could serve as a terminal κ-P, bridging μ2-P,P and chelating κ2-N,N ligand in the complexes [W(CO)5(κ-P-Bdapm)]
摘要研究了多齿配体双(1,2,4-二氮杂磷酰基)甲烷(Bdapm)对6族和10族金属的配位行为。从与[W(CO)5(NMe3)]的反应中,分离和表征了三种具有不同配位方式的物种。因此,我们证明了多齿Bdapm配体可以作为末端κ-P,桥接复合物[W(CO)5(κ-P-Bdapm)]中的μ2-P,P和螯合κ2-N,N配体, [W(CO)5] 2(μ2-P,P-Bdapm)}和W(CO)4(κ2-N,N-Bdapm)}。在钼(II)和镍(II)衍生物[Mo(η3-C3H5)(κ2-N,N-Bdapm)(CO)2Cl]和[Ni( acac)2(κ2-N,N-Bdapm)]。Bdapm与[M(C,N-Ar)Cl]片段来源的反应[Ar = 2-(N,N-二甲基氨基甲基)苯基或2-(N,N-二甲基氨基甲基)二茂铁基,M = Pd或Pt]给出不稳定的κ-P键结合物种,这些物种很容易转化为多金属配合物
