organic compounds
The structures of two 6-aminouracil dimethylacetamide monosolvates and a 1-methylpyrrolidin-2-one monosolvate display N-HO hydrogen-bonding patterns that link the uracil molecules to their respective solvent molecules. The formation of (8) N-HO hydrogen-bond motifs between 6-aminouracil molecules can only be found in two-dimensional frameworks, whereas (14) N-HO patterns are present when zigzag chains of 6-aminouracil molecules are formed.
