The complexes [M(η4-PP3)Cl]Cl (M = Ni, Pd or Pt, PP3
= P(CH2CH2PPh2)3) were treated with the metal based nucleophiles [Pt(PPh3)2(C2H4)], [Pt(η2-bicyclo(2.2.1)hept-2-ene)3] or [Pd2(dba)3] (dba = dibenzylideneacetone) to produce PP3 bridged metal–metal bonded homo- and heterodinuclear complexes in which the central and one terminal phosphorus of the PP3 ligand are chelated to one metal whilst the other two terminal phosphorus atoms bridge to the second metal centre. The products are characterised by 31P and 195Pt NMR spectroscopy; X-ray crystal structures were determined for [Pt2(PP3)(PPh3)Cl]Cl and [Pd2(PP3)Cl2].
配合物 [M(η4-PP3)Cl]Cl(M = Ni、Pd 或 Pt,PP3 = P(CH2CH2PPh2)3)与金属基亲核物 [Pt(PPh3)2(C2H4)]、[Pt(η2-双环(2.2.1)庚-2-烯)3]或[Pd2(dba)3](dba = 二亚苄基丙酮)来生成 PP3 桥接金属-金属键的同核和异核配合物,其中 PP3 配体的中心磷和一个末端磷与一种金属螯合,而另外两个末端磷原子则与第二种金属中心桥接。这些产物通过 31P 和 195Pt NMR 光谱进行表征;[Pt2(PP3)(PPh3)Cl]Cl 和 [Pd2(PP3)Cl2]的 X 射线晶体结构已经确定。
