(1) C12H9BrN2O, M(r) = 277.3, monoclinic, P2(1)/n, a = 8.167 (3), b = 17.541 (5), c = 8.457 (3) angstrom, beta = 114.67 (3)degrees, V = 1100 (2) angstrom 3, Z = 4, D(x) = 1.67 Mg m-3, lambda(Mo K-alpha) = 0.71069 angstrom, mu = 0.367 mm-1, F(000) = 552, room temperature, R = 0.041 for 1194 unique observed reflections. The exocyclic C and the pyridine N atoms are in cis positions. A strong intramolecular O-H...N bond [O...N = 2.619 (8) angstrom] leads to the formation of a supplementary ring. The molecule is not planar; the pyridine ring is inclined at 5.20-degrees to the phenyl ring, and at 6.1-degrees to the hydrogen-bonded ring. |
