The crystal structure of the title compound has been determined by single crystal X-ray diffraction analysis. C15H14N4O3, M-r = 298. 30, monoclinic, space group P2(1)/n, a = 9. 483 (9), b = 11. 078 (9), c = 13. 700 (9) Angstrom, beta = 100. 19 (7)degrees, V = 1417 (4) Angstrom(3), Z = 4, D-x = 1. 399 g. cm(-3), mu = 0. 0942 mm(-1); F(000) = 624, final R = 0. 074 and R-w = 0. 074 for 1502 observed reflections [I greater than or equal to 3 sigma(I)]. The results show that all ring atoms in the triazolopyrimidinyl moiety were coplan...
