A polymeric zinc thio­sulfate complex containing anionic and cationic chains based on tetra­hedral and octa­hedral zinc sites

catena‐Polytetra­aqua­zinc(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.
