The title co‐crystal, C 4 H 4 FN 3 O·C 4 H 4 FN 3 O·H 2 O, has one molecule of 4‐amino‐5‐fluoropyrimidin‐2(1 H )‐one, one molecule of its isomer 2‐amino‐5‐fluoropyrimidin‐4(3 H )‐one and a molecule of water in the asymmetric unit. 4‐Amino‐5‐fluoropyrimidin‐2(1H)‐one is commonly known as 5‐fluorocytosine.
