摘要：
N-2,N-6-bis(m-nitrobenzylidene)pyridine-2,6-dicarbohydrazid (a), N-2,N-6-bis(p-nitro benzylidene)pyridine-2,6-dicarbohydrazid (b), and N-2,N-6-bis(p-chlorobenzylidene) pyridine-2,6-dicarbohydrazid (c) were synthesized and characterized by H-1 NMR, Mass Spectroscopy, and Infrared Spectroscopy. The single crystals of compound C27H29N9O11 (1), C27H29N9O11 (2), and C21H15Cl2N5O4 (3) were characterized by X-ray single-crystal diffraction analysis. The crystal structure analysis revealed that compound 1 crystallizes in a monoclinic system, space group C2/c, a = 24.6504(10) angstrom, b = 10.4624(6) angstrom, c = 14.4850(6) angstrom. The compound 2 crystallizes in monoclinic system, space group C2/c, a = 24.6505(9) angstrom, b = 10.4618(4) angstrom, c = 14.4946(5) angstrom. The compound 3 crystallizes in a monoclinic system, space group P2 (1)/n, a = 8.6377(9) angstrom, b = 14.4815(15) angstrom, c = 17.6598(19) angstrom.
