摘要：

C6H4N4O2, M(r) = 164.12, orthorhombic, Pcab, a = 13.602 (1), b = 14.477 (2), c = 6.969 (1) angstrom, V = 1372.3 (3) angstrom3, Z = 8, D(x) = 1.589 Mg m-3, lambda(Cu K-alpha-1) = 1.54050 angstrom, mu = 1.025 mm-1, F(000) = 672, T = 295 K, final R = 0.049 for 692 reflections. The benzotetrazine ring is planar indicating extensive pi-electron delocalization. Shortened semipolar N-O bonds [N(2)-O(5) 1.255 (4) and N(4)-O6) 1.238 (4) angstrom] were observed.
