of the bidentate ligand 2, 11-bis(diphenylarsinomethyl)benzo-[c]-phenanthrene (1) is described. This ligand reacts with appropriate substrates to give mononuclear square planar complexes of type [MX2(1)] (M = Pd, Pt; X = Cl, Br, I) and [M′Cl(CO)(1)] (M′ = Rh, Ir) in which ligand 1 spans trans-positions. This is confirmed by the crystal structure of [PtCl2(1)]. 1H-NMR. spectra of the complexes are discussed
描述了双齿配体2、11-双(二苯基ar基甲基)苯并-[ c ]-菲(1)的制备。该配体与合适的底物反应,得到[MX 2(1)](M = Pd,Pt; X = Cl,Br,I)和[M'Cl(CO)(1)](M ′= Rh,Ir),其中配体1跨越转位。[PtCl 2(1)]的晶体结构证实了这一点。1 H-NMR。讨论了配合物的光谱,并与模型化合物反式-[MCl 2(12)2的光谱进行了比较。](M = Pd,Pt)和[M'Cl(CO)(12)2 ](M′= Rh,Ir;12= AsBzPh 2)。
