Abstract: In the crystal structure of the title compound, [Co₂(SO₄)₂(C₅H₅N)₆(H₂O)₂]·4H₂O, the sulfate dianion bridges a (C₅H₅N)₄Co unit to a (C₅H₅N)₂(H₂O)₂Co unit, forming a chain that runs along the a axis of the monoclinic unit cell. The Co atoms of the units lie on special positions, each of $\overline{1}$ site symmetry. Adjacent chains are linked through the uncoordinated water molecules into layers.
