catena‐Poly[[[aqua(ethylenediamine‐κ2N,N′)(nitrato‐κO)copper(II)]‐μ‐4,4′‐dithiodipyridine‐κ2N:N′] nitrate monohydrate]

The title compound, {[Cu(NO₃)(C₂H₄N₂)(C₁₀H₈N₂S₂)(H₂O)]NO₃·H₂O}_n, is composed of a one‐dimensional linear coordination polymer involving cis‐protected copper(II) ions and a 4,4′‐dithiodipyridine bridging ligand. The polymeric chains run along the c‐axis direction. N—H...O and O—H...O hydrogen bonds involving the coordinating amine groups, nitrate ions and water molecules, as well as cocrystallized noncoordinating nitrate ions and water molecules, generate a three‐dimensional structure.
