Figure 2
Difference Fourier maps (a) of the high-temperature phase, (b) of the low-temperature phase and (c) associated with the N⋯H⋯O hydrogen bond between the pyrimidine and water molecules. Maps were calculated on the mean plane of O5/N1/C7 or O10/N3/C17 from a model containing all atoms apart from the H atom in the hydrogen bond. The contours are at 0.03 e Å−3 in (a) and 0.05 e Å−3 in (b) and (c), and dashed lines indicate negative contours. |
