摘要：

C10H9N3, M(r) = 171.21, triclinic, P1BAR, a = 8.229 (2), b = 10.654 (3), c = 10.668 (2) angstrom, alpha = 92.93 (2), beta = 93.01 (2), gamma = 107.5 (2)-degrees, V = 888.6 angstrom 3, Z = 4, D(x) = 1.28 g cm-3, lambda(Mo K-alpha) - 0.71073 angstrom, mu = 0.8 cm-1, F(000) = 360, T = 296 (1) K, R = 0.041 for 1788 unique observed reflections. The structure consists of hydrogen-bonded dimeric molecules. The dihedral angles between the pyridyl rings in the two monomeric units are distinctly different [7.0 (5) and 28.8 (1)-degrees].
