catena-Poly[[(acetato-κ2O,O′)[2-(4-oxo-1,4-dihydroquinolin-1-yl)acetato-κO1]copper(II)]-μ-4,4′-bipyridine-κ2N:N′]

In the title compound, [Cu(C11H8NO3)(CH3COO)(C10H8N2)]n, the CuII ion is six-coordinated by two N atoms from two 4,4′-bipyridine ligands, four O atoms from one acetate ligand, one 2-(4-oxo-1,4-dihydroquinolin-1-yl)acetate ligand and one water molecule in a distorted octahedral geometry. The 4,4′-bipyridine ligands interconnect [Cu(C11H8NO3)(CH3COO)] units, giving rise to a chain along [010]. These chains are further linked to each other by O—H...O hydrogen bonds, leading to a two-dimensional supramolecular network parallel to (100).
