The crystal packing of (II)[link], depicting the cytosinium–cytosine base pairs and their connection to adjacent nicotinate anions and water mol­ecules via hydrogen-bonded linkages. H atoms not involved in hydrogen bonding have been omitted for clarity. Only atoms connecting the planes are labelled.
