In the title compound, [Co(C14H16N2O4)2(H2O)2]n, the CoII atom, lying on an inversion center, is coordinated by six O atoms in a distorted octa­hedral geometry. The CoII atoms are bridged by the nitronyl nitroxide ligands into a tape-like structure along the b axis. The tapes are further connected by O—H⋯O hydrogen bonds, forming a layer parallel to the bc plane.
