ΔΔ-[Ni{Co(aet)2(R-pn)}2]4+与等摩尔Na2[PdCl4]在水中的取代反应选择性地得到了具有光学活性的三核配合物ΔΔ-[Pd{Co(aet)2(R-pn)}2]4+(1)。另一方面，在相同的反应条件下，通过Na2[PdCl4]的两摩尔等量加成，得到了具有光学活性的双核配合物Δ-[PdCl2{Co(aet)2(R-pn)}]+(2)。同样，ΔΔ-[Ni{Co(aet)2(R-pn)}2]4+与两个摩尔当量的[Pd(NO3)2(bpy)]反应生成了具有光学活性的双核配合物Δ-[Pd(bpy){Co(aet)2(R-pn)}]3+(3)。配合物1、2和3的晶体结构用x射线晶体学测定。1、2和3中的每个Co原子都由两个aet和一个R-pn配体配位，形成近似八面体的几何形状。1中的Pd原子由两个顺式(S)-[Co(aet)2(R-pn)]+单位的4个S原子配位。2中的钯原子由一个顺式(S)-[Co(aet)2(R-pn)]+单位的两个S原子和两个Cl原子连接，而3中的钯原子由一个顺式(S)-[Co(aet)2(R-pn)]+单位的两个S原子配位。
The substitution reaction of ΔΔ-[Ni{Co(aet)2(R-pn)}2]4+ with equimolar Na2[PdCl4] in water gave selectively an optically active trinuclear complex, ΔΔ-[Pd{Co(aet)2(R-pn)}2]4+ (1). On the other hand, an optically active dinuclear complex, Δ-[PdCl2{Co(aet)2(R-pn)}]+ (2), was also obtained by a two-molar equivalent addition of Na2[PdCl4] under the same reaction condition. Similarly, the reaction of ΔΔ-[Ni{Co(aet)2(R-pn)}2]4+ with two molar equivalent [Pd(NO3)2(bpy)] produced an optically active dinuclear complex, Δ-[Pd(bpy){Co(aet)2(R-pn)}]3+ (3). The crystal structures of complexes 1, 2, and 3 were determined by X-ray crystallography. Each of the Co atoms in 1, 2, and 3 is coordinated by two aet and one R-pn ligands to take an approximately octahedral geometry. The Pd atom in 1 is coordinated by four S atoms from two cis(S)-[Co(aet)2(R-pn)]+ units. The Pd atom in 2 is ligated by two S atoms from one cis(S)-[Co(aet)2(R-pn)]+ unit and two Cl atoms, while the Pd atom in 3 is coordinated by two S atoms from one...
