Abstract

C12H7N2F, M(r) = 198.20, monoclinic, C2/c, a = 11.296 (4), b = 8.471 (3), c = 18.889 (2) angstrom, beta = 98.83 (2)-degrees, V = 1786.0 (2) angstrom 3, Z = 8, D(m) = 1.45, D(x) = 1.474 g cm-3, lambda-(Cu K-alpha) = 1.54180 angstrom, mu-(Cu K-alpha) = 8.284 cm-1, F(000) = 816, T = 293 K, R = 0.051 for 1378 observed unique reflections [I greater-than-or-equal-to 3-sigma-(I)]. The rings in the benzo[c]cinnoline skeleton are close to planar with dihedral angles of 0.45 (7)-1.17 (8)-degrees. The F atom is located 0.004 (3) angstrom from the least-squares plane of the benzenoid ring.
