摘要：
Cytosine-cytosinium base pairs are interconnected by triple hydrogen bonds thereby resembling a pseudo-Watson-Crick pattern and generates two characteristic R22(8)-motifs. Both molecules of the salicylic acids interconnect the base pair and lead to the formation of one dimensional supramolecular hexameric tape along b-axis. This hexameric tape are sandwiched by the water molecules, one of the salicylic acid and salicylate anion which form one dimensional and two dimensional supramolecular hydrogen bonded networks in the crystal packing. Macrocylic rings of cavities are also noticed in the crystal structure.
