Abstract: The title compound, {[Cu(C₁₀H₈N₂)(NO₃)₂(H₂O)₂]·0.5H₂O}_n, has a linear polymeric structure, with the bridging ligand 4,4'-bipyridine (bipy) connecting the Cu^II ions. Each ion lies on an inversion center and has a distorted octahedral environment, being coordinated by two bipy ligands, two nitrate anions and two water molecules [Cu-N = 2.010 (3) Å and Cu-O = 1.981 (3) and 2.414 (3) Å]. In the crystal structure, the linear polymeric chains, propagating in two directions, are linked by intermolecular O-HO hydrogen bonds, resulting in a three-dimensional supramolecular network, which has channels parallel to the c axis containing the water molecules of crystallization. The water molecule is equally disordered over two positions.
