The title compound, {[Co(C10H8N2)2(H2O)2](NO3)2·4H2O}n, (C10H8N2 = 4,4'-bipyridine = 4,4'-bpy) is a layered coordination polymer built up from a cationic square grid extending in (101) enclosing uncoordinating nitrate ions and water molecules. The CoII ion has site symmetry 2 and one of the 4,4'-bpy ligands is generated by twofold symmetry [two N atoms and two C atoms lie on the rotation axis and the dihedral angle between the pyridine rings is 45.66 (5)°]. The other 4,4'-bpy ligand is generated by a crystallographic inversion center. The CoII ion exhibits a slightly distorted octahedral coordination geometry defined by two O atoms of two coordinating water molecules and four N atoms from four bridging 4,4'-bpy ligands. The structure is consolidated by O-H...O, C-H...O and C-H...N hydrogen bonds.
