In the title compound, [Co2(SO4)2(C10H8N2)2(C2H6O2)2(H2O)2]n, there are two crystallographically independent CoII ions, each of which lies on a twofold rotation axis and has a slightly distorted octahedral environment. One CoII ion is coordinated by two N atoms from two bridging 4,4'-bipyridine (4,4'-bipy) ligands, two O atoms from two sulfate ions and two O atoms from aqua ligands. The second CoII ion is similar but with ethane-1,2-diol ligands in place of water molecules. The sulfate anions act as bridging ligands to link two adjacent CoII ions together, leading to the formation of linear ...Co1Co2Co1Co2...chains along the a axis. Adjacent chains are further bridged by 4,4'-bipy ligands, which are also located on the twofold rotation axis, resulting in a two-dimensional layered polymer extending parallel to (001). In the crystal, the layers are linked by extensive O-H...O hydrogen-bonding interactions involving the O atoms of the water molecules and ethane-1,2-diol molecules, resulting in a three-dimensional supramolecular network.
