A number of bis[palladium(II)] and bis[platinum(II)] complexes of the type [(MCl2)2(μ-quadridentate)] [where M = Pd(II) or Pt(II)] and [(PtClMe)2(μ-quadridentate)] have been prepared containing the linear quadridentate NPPN ligands 1,3-bis[(2-aminophenyl)phenylphosphino]propane, 1; 1,4-bis[(2-aminophenyl)phenylphosphino]butane, 2; 1,5-bis[(2-aminophenyl)phenylphosphino]pentane, 3 [Pd(II) only]; 1,
[[MCl 2)2(μ-四齿)]类型的许多双[钯(II)]和双[铂(II)]络合物[其中M = Pd(II)或Pt(II)]和[ (PtClMe)2(μ-四齿)]已经制备含有线性四齿配体NPPN 1,3-双[(2-氨基苯基)苯基膦基]丙烷,1 ; 1,4-双[(2-氨基苯基)苯基膦基]丁烷,2 ; 1,5-双[(2-氨基苯基)苯基膦基]戊烷,3 [仅Pd(II)];1,6-双[(2-氨基苯基)苯基膦基]己烷,4 ; 1,3-双[(2-氨基乙基)苯基膦基]丙烷5; 以及相关的PNNP配体1,3-双[(2-二苯基膦基苯基)氨基]丙烷,6;和1,2-双[(2-二苯基膦基苯基)氨基]乙烷,7 [仅Pt(II)]。外消旋的分离和内消旋线性四齿NPPN配体的非对映体和(的分辨率- [R P *,- [R P *) - 1已经实现通过由一对双的分步结晶分离[钯(II含有)]配合物各自的配体和正金属化的N
