Extensive C—H⋯O, N—H⋯O, and O—H⋯O hydrogen bonding, represented by dashed red lines, links the anions, complex cations, and water molecules into sheets parallel to the ab plane. For clarity, the pyridine C and H atoms not involved in hydrogen-bonding interactions have been omitted, and only the N atom coordinating to the CoIII cation is shown for the azide anions.
