摘要
Three uracil derivatives of methyl 3-(2,4-dioxo-3,4- dihydropyrimidin-1(2H)-yl) propanoate (I), methyl 3-(5-nitro- 2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl) propanoate (II) and ethyl 3-(5-nitro-2,4-dioxo-3,4-dihydropyrimidin-1 (2H)-yl) propanoate (III) have been prepared through one pot synthesis and examined by X-ray crystallography, FT-IR and NMR spectroscopy. Compound I, C8H10N2O4, is monoclinic with space group P 21/c and cell constants a = 11.4437(12), b = 11.7980(13), c = 6.9496(7) angstrom, beta = 103.180(2)degrees, V = 913.57(17) angstrom(3), and Z = 4. Compound II, C8H9N3O6, crystallizes in the monoclinic P 21 space group with cell constants a = 8.0342(14), b = 5.7155(10), c = 11.572(2) angstrom, beta = 105.200(3)degrees, V = 512.79(16) angstrom(3), and Z = 2. Compound III, C9H11N3O6, is Orthorhombic with space group P 212121 and cell constants a = 5.7560(16), b = 8.032(2), c = 25.302(7) angstrom, beta = 90 degrees, V = 1169.8(6) angstrom(3), and Z = 4. The supramolecular architectures of the three compounds involve N-H center dot center dot center dot O hydrogen bond.
