Abstract
At the molar ratio of 1∶ 1.2 and 80 ℃,a novel crystal 2,2'-(3-nitro-4-chlorobenzyl) methylene bis(3-hydroxy-5,5-dimethyl-2-cyclohexene-1-one),was synthesized through reacting 3-nitro-4chlorobenzaldehyde with 5,5-Dimethyl-1,3-cyclohexanedione using DMF as the solvent for 1 h in the absence of any catalyst.The structure was characterized by melting points,elemental analysis,IR,1H NMR and X-ray single crystal diffractometer.The result shows the crystal in monoclinic crystal system and P21/ n space group.Crystallographic date: a = 1.95777(13) nm,b = 1.22720(9) nm,c = 1.99687(14) nm,β = 107.719(2) °,V = 4.5700(6) nm3,Z =8,dC = 1.302 g / m3,μ =0.205 mm-1,F(000) =1888.
