Figure 3From: 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 Part of the crystal structure of CytNit, viewed perpendicular to the (100) plane. Displacements ellipsoids are drawn at 50% probability level and H atoms as small spheres of arbitrary size. Hydrogen bonds are indicated by double dashed lines.Back to article page
