Site Selectivity of Halogen Oxygen Bonding in 5- and 6-Haloderivatives of Uracil
Crystals, 2019 Seven 5-and 6-halogenated derivatives of uracil or 1-methyluracil (halogen = Cl, Br, I) were studied by single crystal X-ray diffraction. In contrast with pure 5-halouracils, where the presence of N-H⋯O and C-H⋯O hydrogen bonds prevents the formation of ...
