The reactions of the Delta L and Lambda L isomers of [Co( l-Hcys- N, S)(en) 2] (2+) ( l-H 2cys = l-cysteine) with CuCl in aqueous HCl gave Co (III)Cu (I) dinuclear complexes with the same S-bridged structures, Delta L- 1 and Lambda L- 1. When Delta L- 1 was treated with CdCl 2 in water, a 1D wavelike (Co (III) 2Cd (II)Cu (I)) n polymeric complex ( 2) was produced. On the other hand, similar treatment of Lambda L- 1 led to the formation of a 2D honeycomb-like (Co (III) 3Cd (II) 3Cu (I)) n polymeric complex ( 3), supported by the presence of counter-monoanions.
Co(l-Hcys-N,S)(en)₂（l-H₂cys = l-半胱氨酸）的ΔL和ΛL异构体与HCl水溶液中的CuCl反应，生成具有相同S桥连结构的Co(III)Cu(I)双核配合物，即ΔL-1和ΛL-1。当在水中用CdCl₂处理ΔL-1时，会生成一维波状(Co(III)₂Cd(II)Cu(I))ₙ聚合物配合物(2)。另一方面，对ΛL-1进行类似处理会导致形成二维蜂窝状(Co(III)₃Cd(II)₃Cu(I))ₙ聚合物配合物(3)，这是由抗衡单阴离子的存在所支撑的。
