摘要

A novel compound PMPP-SAL (1-phenyl-3-methyl-4-(salicylidene hydrazide)-propenylidene-pyrazolone-5) has been synthesized and characterized by elemental analysis, IR, 1H NMR and single-crystal X-ray diffraction. The X-ray diffraction reveals that the compound is of orthorhombic, space group Pbca with a = 16.132(5), b = 10.113(3), c = 23.143(7) (A), V = 3776(2) (A)3, Z = 8, C20H20N4O3, Mr= 364.40, Dc = 1.282 g/cm3, F(000) = 1536, μ(MoKα) = 0.089 mm-1, S = 0.992, R = 0.0578 and wR = 0.1362 for 1871 observed reflections with I ＞ 2σ(Ⅰ). In the crystal, the compound possesses two C=O bonds and exists in the NH-form' other than NH-form.
