Abstract: The organic components of 2-methoxy-3-methyl-6-oxo-4-(2,3,4-tri-O-acetyl--D-xylopyranosylamino)-1,6-dihydropyrimidine-5-carbaldehyde 0.065-hydrate, C₁₈H₂₃N₃O₁₀·0.065H₂O, (I), which crystallizes with Z' = 2 in the space group P2₁2₁2₁, are linked into a three-dimensional framework structure by a combination of four C-HO hydrogen bonds. In 2-methylsulfanyl-6-oxo-4-(2,3,4-tri-O-acetyl--D-xylopyranosylamino)-1,6-dihydropyrimidine-5-carbaldehyde, C₁₇H₂₁N₃O₉S, (II), where the pyrimidine fragment is disordered with two different conformations for the methylsulfanyl substituent, molecules are linked into chains of rings by a combination of N-HO and C-HO hydrogen bonds.

Formula: C₁₈H₂₃N₃O₁₀·0.065H₂O and C₁₇H₂₁N₃O₉S
