Ir), square planar [NiX2(L1)] (X = Cl or Br), [M?Cl2(L1)] (M? = Pd or Pt), the chloro-bridged [Pd2Cl2(L1)2]2+, [Pd(L1)2]2+, the tetrahedral [M?(L1)2]+ (M? = Cu, Ag or Au) and the dinuclear [(AuCl)2(L1)]. Chemical oxidation of some of the complexes are described, giving examples of Co(III), Ni(III) and Pt(IV) species. Where possible the products have been characterised by IR, UV–vis, NMR (1H, 31P, 63Cu
为了研究膦的空间需求及其对不同氧化的灵活性的影响,已经对第9-11组的金属离子研究了广角二膦o-C6H4(CH2PPh2)2(L1)的系统配位化学状态和协调几何。分离出的产物包括四面体[CoX2(L1)](X = Cl,Br或I),非常扭曲的正方形平面[Rh(L1)2] +,[M(cod)(L1)] +(M = Rh或Ir),正方形平面[NiX2(L1)](X = Cl或Br),[M2Cl2(L1)](M2 = Pd或Pt),氯桥联[Pd2Cl2(L1)2] 2+ ,[Pd(L1)2] 2+,四面体[M2(L1)2] +(M2 = Cu,Ag或Au)和双核[(AuCl)2(L1)]。描述了某些配合物的化学氧化,给出了Co(III),Ni(III)和Pt(IV)物种的实例。在可能的情况下,通过IR,UV-vis,NMR(1H,31P,63Cu和195Pt(如适用)光谱分析,质谱分析和微量分析
