Synthesis and Crystal Structure of (3,6-Dichloro-2-nitrophenyl)(3-nitrophenyl)methanone

O621.3; Novel compounds, (3,6-dichloro-2-nitrophenyl)(3-nitrophenyl)methanone(2), (2-amino-3,6-dichloro- phenyl)(3-aminophenyl)methanone(3) and 1-[3-(2-amino-3,6-dichlorobenzoyl)phenyl]-1H-pyrrole-2,5-dione(4), were synthesized from the initial compound 2,5-dichiorobenzophenone(1) and characterized by C NMR, IR, mass spectrum and element analysis, respectively. The single crystal of compound 2 was obtained and determined by X-ray diffraction analysis. The single crystal data illustrates that it belongs to the monoclinic system, space group P2/c with a=0.7587(4) nm, b=2.4724(4) nm, c=0.8081(3) nm, α=90°, β=112.85(2)°, y=90°, V=1.3970(9) nm, M(CHClNO)=341.10,/μ(Mo Kα)=0.49 mm
