Abstract

The crystal structure of 3-methyluracil has been determined ab initio by conventional monochromatic X-ray powder Ê), V 571.45(3) (A Rdiffraction data. The crystal data are: orthorombic, a 6.6294(1), b 13.1816(3), c 6.53938(9) (AÊ 3), space group Pbnm, Z 8. The structure was solved by direct methods and the ®nal Rietveld re®nement converged to p 0.0398, Rwp 0.0528, RBragg 0.0294. The crystal structure exhibits endless chains of planar molecules, connected via head-to-tail N±H´´´O hydrogen bonds.
