catena-Poly[[[tetraaquazinc(II)]-μ-4,4′-bipyridine-κ2N:N′] [[μ-thiosulfato-κ2O:S-bis[(thiosulfato-κS)zinc(II)]]-di-μ-4,4′-pyridine-κ4N:N′] dihydrate], {[Zn(C10H8N2)(H2O)4][Zn2(S2O3)3(C10H8N2)2]·2H2O}n, is a polymeric zinc complex built up from thiosulfate-containing anionic chains, where the Zn atom is tetrahedrally coordinated, and aqua-containing cationic chains incorporating octahedrally coordinated Zn. In each type of chain, the 4,4′-bipyridine units act as spacers, and the chains run along three non-intersecting almost orthogonal directions in space. The profusion of hydrogen-bond donors (all the H atoms of the water molecules) and acceptors (the thiosulfate O and S atoms) generates a very complex hydrogen-bonding scheme.
