It crystallizes in the monoclinic system, space group P 21 /n, a=7.1257 (15), b=8.351 (3), c=21.520 (4) Å, β=92.89 (8)°, V=1279.0 (6) Å3, Z=4. The structure consists of triple hydrogen-bonded 5-Fluorocytosine pairs, water molecules and chloride anions. Asymmetric reversed Watson-Crick base pairing occurs between one protonated (5FcytH+) and one neutral 5-Fluorocytosine (5Fcyt) molecule.
