The crystal structures of two complexes containing the peroxodisulfate anion are reported, namely mu-peroxodisulfato-1kappaO:2kappaO'-bis[(acetato-kappa2O,O')aqua(2,2':6',2''-terpyridine-kappa3N,N',N'')cadmium(II)] heptahydrate, [Cd2(C2H3O2)2(S2O8)(C15H11N2)2(H2O)2].7H2O, (I), and catena-poly[[[bis(2,2'-bipyridine-kappa2N,N')mercury(II)]-mu-peroxodisulfato-kappa2O:O'] 0.4-hydrate], {[Hg(C10H8N2)2(S2O8)].0.4H2O}n, (II). In both structures, the anion behaves as a bridge, linking neighbouring coordination polyhedra in two different ways, either tightly bound to the heptacoordinated Cd2+ cation forming neatly separated dimeric entities in (I) or across a shorter O-S-O path producing weakly connected chains by way of 'semicoordination' to the Hg2+ cations in (II).
报道了两种含有过二硫酸根阴离子的配合物的晶体结构，即μ-过二硫酸根-1κO:2κO'-双[(乙酸根-κ2O,O')水合(2,2':6',2''-三联吡啶-κ3N,N',N'')镉(II)]七水合物，[Cd2(C2H3O2)2(S2O8)(C15H11N2)2(H2O)2]·7H2O，(I)，以及链状聚[[[双(2,2'-联吡啶-κ2N,N')汞(II)]-μ-过二硫酸根-κ2O:O']0.4水合物]，{[Hg(C10H8N2)2(S2O8)]·0.4H2O}n，(II)。在这两种结构中，阴离子均起到桥连作用，以两种不同方式连接相邻的配位多面体，在(I)中紧密结合到七配位的Cd2+阳离子上，形成排列整齐的分离二聚体实体，或者在(II)中通过较短的O-S-O路径，以“半配位”方式与Hg2+阳离子形成弱连接的链。
