摘要：

The title Schiff base compound (C11H8N4O), a derivative of pyrazole, has been synthesized by the reaction of salicylaldehyde and 3-amino-4-cyanopyrazole in absolute ethanol and characterized by elemental analyses, IR, H-1 NMR and X-ray single-crystal diffraction. The crystal belongs to the monoclinic system, space group P2(1)/n, with a = 7.5594(7), b = 18.3342(19), c = 22.461(2) angstrom, beta = 98.419(2)degrees, V = 3079.5(5) angstrom(3), M-r = 212.21, Z 12, F(000) = 1320, D-c = 1.373 g/cm(3), T = 298(2) K, lambda = 0.71073 angstrom, the final R = 0.0571 and wR 0.0493. A total of 5412 unique reflections were collected, of which 1612 with I > 2 sigma(I) were observed. The molecular structure adopts a trans configuration about the C=N double bond. The preliminary biological tests show that the compound has high antibacterial activities.
