Figure 4From: Solid-phase molecular recognition of cytosine based on proton-transfer reaction. Part II. supramolecular architecture in the cocrystals of cytosine and its 5-Fluoroderivative with 5-Nitrouracil The asymmetric unit of 5FcytNit, showing the atom-labeling scheme and hydrogen bonding (double dashed lines). Displacements ellipsoids are drawn at 50% probability level and H atoms as small spheres of arbitrary size.Back to article page
