4-Thiouridine, Crystal Packing Forces, Molecular Structures 4-thiouridine crystallizes from butyric acid in the form of yellow needles, monoclinic space group P2 j with a = 10.136 (3), b = 4.843 (2 ), c = 11.257 (3) A, ß = 93.91 (5) °. The crystal structure was solved on the the basis of 895 X-ray counter data using direct methods and refined to a reliability index of R = 5.6%. 4-thiouridine is...
