摘要：

C4H4N2, M(r) = 80.09, monoclinic, P2(1)/n, a = 3.7870 (6), b = 10.7415 (29), c = 9.721 (6) angstrom, beta = 91.401 (27)-degrees, V = 395.32 angstrom 3, Z = 4, D(x) = 1.346 Mg m-3, lambdaBAR(Mo K-alpha) = 0.71073 angstrom, mu = 0.083 mm-1, F(000) = 168, T = 100 K, R = 0.0495 for 1732 unique observed reflections. The observed valence angles agree very closely with those measured for free pyridazine studied by combined analysis of electron diffraction, microwave and liquid-crystal NMR data, but there are significant differences in bond lengths, which can probably be attributed to crystal packing effects.
