The crystal structures of two complexes containing the peroxodisulfate anion are reported, namely μ-peroxodisulfato-1κO:2κO′-bis[(acetato-κ2O,O′)aqua(2,2′:6′,2″-terpyridine-κ3N,N′,N″)cadmium(II)] heptahydrate, [Cd2(C2H3O2)2(S2O8)(C15H11N2)2(H2O)2]·7H2O, (I), and catena-poly[[[bis(2,2′-bipyridine-κ2N,N′)mercury(II)]-μ-peroxodisulfato-κ2O: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).
