Abstract: In the title mononuclear complex, [Co(C₆H₄NO₃)₂(H₂O)₂], the six-coordinate Co^II atom assumes an octahedral geometry and is located on an inversion centre. There is a weak - stacking interaction between adjacent pyridyl rings [centroid-to-centroid distance = 3.8067 (17) Å and perpendicular distance = 3.533 Å]. O-HO, N-HO and C-HO hydrogen bonds connect the mononuclear complexes and form a supramolecular three-dimensional structure.
