Synthesis and crystal structure of the Schiff base derived from acetylacetone and benzidine

The schiff base derived from acetylacetone and benzidine has been synthesized and characterized by elemental analysis,IR,1H NMR and single crystal X-ray diffraction analysis.The crystal belongs to triclinic system,the space group is P-1,with the crystal cell parameters a=0.7637(6),b=0.8069(6),c=0.8838(6)nm,α=70.095(2),β=68.809(3),γ=66.769(2)°,V=0.454(6)nm3,Z=1,Dc=1.274g/cm3,Mr=348.43,R1 =0.0607,wR2=0.1859.The structural analysis for the schiff base indicates it exists in the form of enamine in solid state.1D chains have been formed via the intermolecular hydrogen bonds,and the C-H-π interactions between the chains result in a ladder-like layers for the compound.CCDC:672114
