通过fac(S)-[M'(aet)3] (M' = M, Co) 与 Na2[PdCl4]。 1、2和4的分子结构通过X射线衍射测定。在1和2中，形成平行平面的两个Pd原子由两个八面体fac(S)-[M(aet)3]单元和cis(N)-[M(S)2(aet)2]单元的聚集跨越。在这些配合物中，起始 fac(S)-[M(aet)3] 中的 aet 配体之一从 M（= Rh、Ir）原子转移到 Pd 原子。 4中的两个Pd原子通过两个fac(S)-[Co(aet)3]单元和cis(S)-[Pd(aet)2]单元桥联。在该复合物中，两个 aet 配体转移至 Pd 配体。 1中一个非桥接S原子的甲基化反应得到相应的配合物[Pd{Pd(aet)}{Rh(aet)(smaet}{Rh(aet)3}2]5+ (3; smaet = S-甲基-2-氨基乙硫醇)，其结构也通过X射线衍射确定。对于所有配合物，手性构型...
Novel pentanuclear complexes, [Pd{Pd(aet)}{M(aet)2}{M(aet)3}2]4+ (M = Rh (1); Ir (2); aet = 2-aminoethanethiolate) and [Pd2{Pd(aet)2}{Co(aet)3}2]4+ (4), were prepared by the reactions of fac(S)-[M′(aet)3] (M′ = M, Co) with Na2[PdCl4]. Molecular structures for 1, 2 and 4 were determined by X-ray diffraction. In 1 and 2, two Pd atoms forming the parallel planes are spanned by the aggregation of two octahedral fac(S)-[M(aet)3] units and cis(N)-[M(S)2(aet)2] unit. In these complexes, one of the aet ligands in the starting fac(S)-[M(aet)3] transfers from the M ( = Rh, Ir) atom to the Pd one. Two Pd atoms in 4 are bridged by two fac(S)-[Co(aet)3] units and cis(S)-[Pd(aet)2] unit. In this complex, two aet ligands transfer to the Pd one. The methylation reaction for one non-bridging S atom in 1 gave the corresponding complex [Pd{Pd(aet)}{Rh(aet)(smaet}{Rh(aet)3}2]5+ (3; smaet = S-methyl-2-aminoethanethiolate), whose structure was also determined by X-ray diffraction. For all of the complexes, the chiral configura...
