Portalone, Gustavo published the artcileThe crystal structure of 3-methyluracil from X-ray powder diffraction data, Category: pyrimidines, the publication is Journal of Molecular Structure (2002), 608(1), 35-39, database is CAplus.
The crystal structure of 3-methyluracil was determined ab initio from conventional monochromatic x-ray powder diffraction data. The crystals are orthorhombic, space group Pbnm, with a 6.6294(1), b 13.1816(3), c 6.53938(9) (Å); Z = 8. The structure was solved by direct methods and the final Rietveld refinement converged to Rp = 0.0398, Rwp = 0.0528, RBragg = 0.0294. The crystal structure exhibits endless chains of planar mols., connected via head-to-tail N-H…O H bonds.
