[Co（aet）（en）2]（NO3）2的反应（aet = 2-氨基乙硫醇盐）或[Co（aese）（en）2]（NO3）2（aese = 2-氨基-乙烷硒醇盐）与AgNO 3以2：1的比例在水中反应，得到S-或Se-桥连的CoIIIAgICoIII三核配合物：[Ag{Co（aet）（en）2}2]（NO3）5（[1a]（NO3）5）和[Ag{Co（aese）（en）2}2]（NO3）5（[1b]（NO3）5），而相应的1：1反应产生S-或Se-桥连（CoIIIAgI）n链络合物聚合物：[Ag{Co（aet）（en）2}]（NO3）3（[2a]（NO3）3）和[Ag{Co（aese）（en）2}]（NO3）3（[2b]（NO3）3）。单核的[Co（aet或aese）（en）2]（NO3）2和三核的[1a或1b]（NO3）5是外消旋体，而聚合的[2a或2b]（NO3）3结晶为聚集体，得到Δ和Λ异构体的光学活性晶体。用X射线衍射法测定了配合物Λ-[2a]（NO3）3·H2O和Λ-[2b]（NO3）3·H2O的晶体结构。在Λ-[2a]3+或Λ-[2b]3+中，每个八面体Λ-[Co（aet或aese）（en）2]2+单元中的S或Se原子与两个AgI原子结合形成一维（CoIIIAgI）n锯齿形链。在Λ-[2a]3+或Λ-[2b] 3+中的每个AgI原子，
The reactions of [Co(aet)(en)2](NO3)2 (aet = 2-aminoethanethiolate) or [Co(aese)(en)2](NO3)2 (aese = 2-amino-ethaneselenolate) with AgNO3 in a 2 : 1 ratio in water gave S- or Se-bridged CoIIIAgICoIII trinuclear complexes: [Ag{Co(aet)(en)2}2](NO3)5 ([1a](NO3)5) and [Ag{Co(aese)(en)2}2](NO3)5 ([1b](NO3)5), while the corresponding 1 : 1 reactions produced S- or Se-bridged (CoIIIAgI)n chain complex-polymers: [Ag{Co(aet)(en)2}](NO3)3 ([2a](NO3)3) and [Ag{Co(aese)(en)2}](NO3)3 ([2b](NO3)3). While the mononuclear [Co(aet or aese)(en)2](NO3)2 and the trinuclear [1a or 1b](NO3)5 were racemates, the polymeric [2a or 2b](NO3)3 crystallized as a conglomerate to give optically active crystals of Δ and Λ isomers. The crystal structures of Λ-[2a](NO3)3·H2O and Λ-[2b](NO3)3·H2O were determined by X-ray crystallography. In Λ-[2a]3+ or Λ-[2b]3+, the S or Se atom in each octahedral Λ-[Co(aet or aese)(en)2]2+ unit is bound to two AgI atoms to form a one-dimensional (CoIIIAgI)n zigzag chain. Each AgI atom in Λ-[2a]3+ or Λ-[2b...
