A one-dimensional coordination polymer incorporating a less common bipyridine isomer: Catena-poly[[bis(acetato-κO)aquacopper(II)]-μ-3, 3′-bipyridine-κN:N′]

The title compound, [Cu(CH₃COO)₂(C₁₀H ₈N₂)(H₂O)]_n, is a one-dimensional coordination polymer containing square-pyramidally coordinated Cu bound to two N atoms from two 3,3′-bipyridine molecules, two O atoms from two distinct monodentate acetate anions, and one O atom from an aqua ligand. Anti-conformation 3,3′-bipyridine units link the Cu^II atoms into chain motifs that run parallel to the a crystal axis. These arrange into layers parallel to the ac crystal plane through supramolecular hydrogen bonding.
