摘要：
4(5)-Nitroimidazole, C3H3N3O2, M(r) = 113.08, monoclinic, P2(1)/n, a = 6.9559 (4), b = 9.9130 (6), c = 7.3045(4) angstrom, beta = 119.41(4)degrees, V= 438.8 (4) angstrom3, Z = 4, D(m)(293 K) = 1.64, D(x) = 1.7117 Mg m-3, lambda(Mo Kalpha) = 0.71069 angstrom, mu = 0.1367 mm-1, F(000) = 232, T = 100 K. Final R = 0.024 for 633 unique observed [F greater-than-or-equal-to 4sigma(F)] reflections. The molecules are planar and are stacked in planes almost parallel to the bc plane. These molecular layers are built up by three hydrogen bonds. 4-5-tautomerism is discussed.
