The title compound (C9H7N3O) has been determined from three dimensional X-ray diffraction data. The crystals are monoclinic, a = 4.858(3) Angstrom, b = 15.008(7) Angstrom, c = 11.787(2) Angstrom, beta = 94.107(2)degrees, V = 857.2(4) Angstrom(3), z = 4, D-calc = 1.342 g.cm(-3) space group P2(1)/c. The structure was solved by direct methods and refined by full-matrix least-squares method (lambda MoKalpha, R = 0.0766).
