catena-Poly[[(2,2′-bipyridine-κ2N,N′)cobalt(II)]-μ-oxalato-κ4O1,O2:O1′,O2′]

In the one-dimensional title coordination polymer, [Co(C2O4)(C10H8N2)]n, the CoII atom is coordinated in a distorted octahedral geometry by two N atoms from one 2,2′-bipyridine ligand and four O atoms belonging to two chelating oxalate ligands. Two neighboring Co centers are bridged by an oxalate ligand, forming a one-dimensional chain structure.
