catena-Poly[[bis-(2,4-dichloro-benzoato)bis-(methanol-κO)cobalt(II)]-μ-4,4'-bipyridine-κN:N'].

In the title compound, [Co(C7H3Cl2O2)2(C10H8N2)(CH3OH)2]n, the CoII ion lies on a twofold rotation axis and is in a slightly distorted octa­hedral CdO4N2 environment, formed by two O atoms from monodentate dichloro­benzoate ligands, two O atoms from methanol ligands, and two N atoms from trans-related 4,4′-bipyridine ligands. The bipyridine ligands also lies on a twofold rotation axis and bridge the CoII ions, forming chains extending along [010]. An intra­chain O—H⋯O hydrogen bond is observed.
