The tripodal ligands NP(3)(tris[2-(diphenylphosphino)ethyl]amine) and PP(3)(tris[2-(diphenylphosphino)ethyl]phosphine), form five-coordinate [Pd(NP(3))X]X [X = Cl (1), Br (2)], [M(PP(3))X]X [M = Pd: X = Cl (4), Br (5), I (6); M = Pt, X = Cl (7), Br (8), I (9)] and four-coordinate[Pd(NP(3))I]I (3) complexes containing three fused rings around the metal. The interaction between Au(tdg)X (tdg = thiodiglycol;
三脚架配体NP(3)(三[2-(二苯基膦基)乙基]胺)和PP(3)(三[2-(二苯基膦基)乙基]膦)形成五配位[Pd(NP(3))X ] X [X = Cl(1),Br(2)],[M(PP(3))X] X [M = Pd:X = Cl(4),Br(5),I(6); M = Pt,X = Cl(7),Br(8),I(9)]和四坐标[Pd(NP(3))I] I(3)配合物,在金属周围包含三个稠环。Au(tdg)X(tdg = thiodiglycol; X = Cl,Br)或AuI与相应离子卤代络合物1-9的化学计量比为1:1的相互作用是通过开环反应并形成异双金属系统而发生的PdAu(NP(3))X(3)[X = Cl(11),Br(12),I(13)],[MAu(PP(3))X(2)] X [M = Pd:X = Cl(14),Br(15),I(16);M = Pt:X = Cl(17),B
